Â© 2016 Elsevier B.V.A high porosity PerliteMetal Syntactic Foam (PMSF) is produced by the precompaction of a packed bed of expanded perlite particles prior to counter gravity infiltration with molten aluminium. The density of the resulting high porosity (>70 vol%) syntactic foam is in the range of 0.72Â¿0.98 g/cm3, depending on the particle precompaction pressure and the number of compaction steps. Compressive testing is carried out following the ISO 13314 standard to characterise the mechanical properties of this novel material. Furthermore, microcomputed tomography scans are performed in order to investigate its mesostructure. The geometrical analysis revealed that the densification procedure generates a porosity gradient in the direction of the compressive force. This gradient is found to affect the deformation mechanism and thus the mechanical properties of high porosity PMSF.

Â© 2016 Elsevier Ltd.Novel foam filled tubes were manufactured via a highly reproducible and cost effective in situ process. Stainless steel tubes were filled with ultralight porous expanded perlite particles and molten aluminium infiltrated the gaps between these particles. During casting, a ternary intermetallic phase was formed between the liquid aluminium and steel tube as a result of a chemical reaction. Quasistatic uniaxial compression testing was applied on the foam, empty tube, and foamfilled tube samples. Additional samples were subjected to quasistatic and dynamic threepoint bending tests. The results of the quasistatic testing indicate that the foam filling improves the energy absorption capacity of tubes by 2.23 and 3.9 times for compressive and bending loading conditions, respectively. The dynamic bending tests indicate that both empty tubes and foam filled tubes exhibit a positive strain rate sensitivity. It is further shown that a larger tube wall thickness increases the energy absorption of both empty and foamfilled tubes. Foamfilling further increases the energy absorption capacity and, more importantly, the energy absorption efficiency. The impact of foam filling is more substantial in the case of tubes with lower thickness.

Â© 2016 Informa UK Limited, trading as Taylor & Francis Group.In this paper, a new, lighter, version of the highly accurate Moleko, Allnatt and Allnatt formalism for describing both tracer (self) and collective diffusion kinetics in multicomponent random alloys is presented. Verification of the resulting expressions is performed by means of kinetic Monte Carlo simulation. The accuracy of the new formalism is much higher than that of the combined Manning and Holdsworth and Elliott formalism discussed recently. Using this formalism the possible range of the tracer diffusion ratio of the highest to the lowest atomic component is examined for equiatomic (or near equiatomic) binary, ternary, quaternary and quinary alloys. It is shown that in the random alloy model, the correlation effect is the highest with a reduction of the fastest tracer diffusion by 40Â¿55%, when moving from two pure metals to their equiatomic binary alloy. By adding the third component (with an intermediate mobility) this effect can be further increased with a possible total reduction of the fastest tracer diffusion by up to 70% (depending on the combinations of mobilities), while adding the fourth component brings this reduction up to 80% and with a possible maximum of up to 85% reduction for the 5component alloy (again depending on the combinations of mobilities). But the slowest diffusing components are not affected by this. This suggests that kinetics arguments alone are not enough for explaining the sluggish diffusion observed of all atomic components in (equiatomic) highentropy alloys.

Â© 2016 Informa UK Limited, trading as Taylor & Francis GroupIn this paper, extensive Monte Carlo simulation results are reported on tracer and collective diffusion correlation effects in the random ternary alloy, as an example of a multicomponent alloy system. The problem of analytically describing both collective and tracer diffusion kinetics is also addressed for the random multicomponent alloy by application of a combination of the Manning theory and Holdsworth and Elliott theory. It is found that the overall results from the combined theory agree reasonably well with Monte Carlo results. This combined approach is much more accurate than ManningÂ¿s approach itself and much more manageable than the almost exact, but unfortunately difficult to use, selfconsistent theory of Moleko, Allnatt and Allnatt. Some relations between the Onsager phenomenological coefficients and tracer diffusion coefficients are derived and are tested with our Monte Carlo data. Good agreement is found.

Â© 2016 Informa UK Limited, trading as Taylor & Francis Group.Equilibrium molecular dynamics simulation in conjunction with the GreenKubo formalism is employed to study the transport properties of a model Ni50Al50 melt with the embeddedatom method potential developed in [G.P. Purja Pun, Y. Mishin, Phil. Mag., 2009, 89, 3245]. The principal objective of the work is to quantitatively characterise and analyse thermotransport in the system, i.e. diffusion driven by a temperature gradient. In addition, direct phenomenological coefficients for mass and thermal transport are also evaluated and analysed in the process. Furthermore, the results obtained are compared with previously published data for a different model of Ni50Al50 melt with an alternative embeddedatom method potential for the alloy as well as with experiment where possible. It is found that both potentials are able to consistently predict both direct transport coefficients over a wide temperature range. However, these two potentials are found to be inconsistent in characterising the crosscoupled heat and mass transport, predicting even different directions (sign) of the heat of thermotransport. The origin of this difference is discussed in the paper in detail.

Â© 2015 Springer Science+Business Media New York Tissue engineering scaffolds are implants that actively support tissue growth whilst providing mechanical support. For optimum functionality, they are designed to slowly dissolve in vivo so that no foreign material remains permanently implanted inside the body. The current study uses a simple degradation model that estimates the change of scaffold geometry due to surface erosion. This model is applied on scaffolds that have been manufactured using the foam replication method. In order to capture their complex geometry, microcomputed tomography scans of samples are obtained. Their change in geometry and degradation of mechanical properties is evaluated using computational analysis. The present investigation found that the mechanical properties such as the quasielastic gradient, 0.2 % offset yield stress and the plateau stress are decreased systematically over a 10week period of immersion time. Deformation analysis on the titania foam scaffold is performed by means of the deformed model obtained from finite element calculations.

Â© 2015 Elsevier B.V.Abstract A novel metallic syntactic foam is produced using a countergravity infiltration casting method. To this end, expanded perlite particles are combined with an aluminium alloy matrix. This enables close control of geometry at a relatively low production cost. The mechanical properties of the material are studied using finite element analysis. Numerical calculation models are generated directly from microcomputed tomography in order to capture their complex internal geometry. For verification purposes, numerical results are compared with experimental measurements of similar samples where available. But in contrast to experimental testing the numerical analysis is nondestructive and hence allows the repeated testing of samples in multiple loading directions. Thus, material anisotropy can be investigated for the first time. To this end, the quasielastic gradient, the 1% offset yield stress and the plateau stresses are obtained from virtual compression tests in three perpendicular directions (one coincides with the casting direction). Results indicate a weak anisotropy of the mechanical properties.

Â© 2015, ASM International.In the present paper (1) the Hall method (HM) (specifically designed for determining the interdiffusion coefficient at the low and high composition limits of the corresponding interdiffusion composition profile) is further developed in order to be applied to the whole composition profile resulting in the Extended Hall method (EHM); (2) A comparative study of the HM, EHM, BoltzmannMatano (BM) and Sauer and Freise (SF) methods is performed using composition profiles generated by computer simulation. The results clearly indicate that the HM/EHM technique is only applicable when the interdiffusion coefficient is constant (i.e. independent of composition) or almost constant at the low composition regions. In all other cases, the BM and SF methods give the best agreement with the input interdiffusion function even at the ends of the composition profiles.

Â© 2015, Springer Science+Business Media New York.This paper addresses the computation of the effective diffusivity in new bioactive glass (BG) based tissue engineering scaffolds. High diffusivities facilitate the supply of oxygen and nutrients to grown tissue as well as the rapid disposal of toxic waste products. The present study addresses required novel types of bone tissue engineering BG scaffolds that are derived from natural marine sponges. Using the foam replication method, the scaffold geometry is defined by the porous structure of Spongia Agaricina and Spongia Lamella. These sponges present the advantage of attaining scaffolds with higher mechanical properties (2Â¿4Â¿MPa) due to a decrease in porosity (68Â¿76Â¿%). The effective diffusivities of these structures are compared with that of conventional scaffolds based on polyurethane (PU) foam templates, characterised by high porosity (>90Â¿%) and lower mechanical properties (>0.05Â¿MPa). Both the spatial and directional variations of diffusivity are investigated. Furthermore, the effect of scaffold decomposition due to immersion in simulated body fluid (SBF) on the diffusivity is addressed. Scaffolds based on natural marine sponges are characterised by lower oxygen diffusivity due to their lower porosity compared with the PU replica foams, which should enable the best oxygen supply to newly formed bone according the numerical results. The oxygen diffusivity of these new BG scaffolds increases over time as a consequence of the degradation in SBF.

Â© 2015 Elsevier B.V.A novel filler material is introduced to produce high strength metalmatrix syntactic foam. Packed beds of pumice particles, a lowcost natural porous volcanic glass, with the size range of 2.84mm were infiltrated with molten aluminium alloy. The resulting syntactic foams were subjected to microstructural observations and chemical analysis. Furthermore, quasistatic compression testing was applied on heat treated samples. The material strength and the deformation mechanism under compressive loading of the pumice particles and foams were investigated. The results indicate that there is a limited chemical reaction between the particles and matrix. The pumice particles considerably enhance the strength of the foam and result in an average plateau stress of 68.25MPa and specific energy absorption of 24.8MJ/m3. Pumice particles show higher strength in the direction of tubular pores. The mechanical anisotropy of pumice particles is likely to cause a slight variation in the directional properties of the foams.

Â© 2014 Taylor & Francis.The phononmediated contribution to the thermal transport properties of liquid NiAl alloy is investigated in detail over a wide temperature range. The calculations are performed in the framework of equilibrium molecular dynamics making use of the GreenKubo formalism and one of the most reliable embeddedatom method potentials for the intermetallic alloy. The phononmediated contribution to the thermal conductivity of the liquid alloy is calculated at equilibrium as well as for the steady state. The relative magnitude of the thermal conductivity decrease induced by the transition to the steady state is estimated to be less than 2% below 2000 K and less than 1% at 3000 and 4000 K. It is also found that the phononmediated contribution to the thermal conductivity of the liquid alloy can be accurately estimated (well within 1%) on the basis of an approximation which invokes the straightforwardly accessible microscopic expression for the total heat flux without demanding calculations of the partial enthalpies needed for the precise evolution of the reduced heat flux (pure heat conduction). On the basis of these calculations, the correspondence between the experimentally observed and modelled kinetics of solidification due to a difference in thermal conductivity is discussed.

Â© 2015 Elsevier Ltd.Abstract This paper addresses the thermal properties of syntactic metal foam made by embedding expanded perlite particles in A356 aluminium matrix. Lattice Monte Carlo (LMC) analyses are conducted to determine the thermal characterisation of the foam. For increased accuracy, the complex geometry of the metallic foam is captured by microcomputed tomography imaging. Using the resulting detailed geometric models, the effective thermal conductivity tensor is computed with possible thermal anisotropy taken into consideration. The numerical results are verified by comparison with experimental measurements. To this end, an improved steadystate method is used to correct for thermal contact resistance. Furthermore, the effective heat capacity, average density and thermal diffusivity of perlite  metal syntactic foam are determined.

Â© 2015 Â© 2015 Taylor and Francis.A recently developed novel approach of simultaneous analysis of isotope and interdiffusion profiles in binary alloy systems is significantly advanced in order to apply to the case of multicomponent alloy systems. The resulting relations for the tracer or selfdiffusion coefficients allow for the avoiding of the explicit solution of the interdiffusion equations. This remarkable result means that in the experimental implementation of this new technique there is no need for multiple diffusion couples. Only two profiles of the same component are necessary for the complete analysis. These can be two different isotopes or just two spatially different parts of the same atomic species. Descriptions of three possible experimental implementations of the novel technique combined with the SauerFreise method are discussed. Therefore, the new development is ready to be applied experimentally and can provide valuable insight into otherwise very difficult diffusion investigations into multicomponent alloys including highentropy alloys.

The recently introduced analytical model for the heat current autocorrelation function of a crystal with a monatomic lattice [Evteev et al., Phil. Mag. 94 (2014) p. 731 and 94 (2014) p. 3992] is employed in conjunction with the GreenÂ¿Kubo formalism to investigate in detail the results of an equilibrium molecular dynamics calculations of the temperature dependence of the lattice thermal conductivity and phonon dynamics in f.c.c. Ni. Only the contribution to the lattice thermal conductivity determined by the phononÂ¿phonon scattering processes is considered, while the contribution due to phononÂ¿electron scattering processes is intentionally ignored. Nonetheless, during comparison of our data with experiment an estimation of the second contribution is made. Furthermore, by comparing the results obtained for f.c.c. Ni model to those for other models of elemental crystals with the f.c.c. lattice, we give an estimation of the scaling relations of the lattice thermal conductivity with other lattice properties such as the coefficient of thermal expansion and the bulk modulus. Moreover, within the framework of linear response theory and the fluctuationdissipation theorem, we extend our analysis in this paper into the frequency domain to predict the power spectra of equilibrium fluctuations associated with the phononmediated heat dissipation in a monatomic lattice. The practical importance of the analytical treatment lies in the fact that it has the potential to be used in the future to efficiently decode the generic information on the lattice thermal conductivity and phonon dynamics from a power spectrum of the acoustic excitations in a monatomic crystal measured by a spectroscopic technique in the frequency range of about 1Â¿20Â¿THz.

Â© 2014 Elsevier Ltd.Packed beds of expanded perlite (EP) particles with three different size ranges (11.4, 22.8, and 45.6. mm) have been infiltrated with molten Al to produce EP/A356 Al syntactic foam. A T6 heat treatment was applied to the foams. The effects of EP particle size on microstructural, geometrical, and mechanical properties of the foams were investigated. The EP particle size determines the number of cells across the sample diameter (725). It also influences the microstructural characteristics of the cellwall alloy and the homogeneity of the cellwall geometry. Enhanced microstructural characteristics and a greater geometrical homogeneity of the cellwall in the case of smaller EP particles result in superior mechanical properties. The compressive deformation becomes more uniform by decreasing the EP particle size resulting in smoother and steeper stressstrain curves. As a result, these foams exhibit higher plateau stresses and improved energy absorption. The number of cells across the sample diameter does not have a significant effect on the mechanical properties of the samples considered.

Â© 2014 Elsevier B.V. All rights reserved.The vibrational contribution to the thermal transport properties of liquid Cu is investigated in detail in the temperature range 13001800 K. The calculations are performed in the framework of equilibrium molecular dynamics making use of the GreenKubo formalism and one of the most reliable embeddedatom method potentials for Cu. It is found that the temporal decay of the heat current autocorrelation function of the liquid Cu model can be described by a single exponential function, which is characterized in the studied temperature range by a constant value of the heat flux relaxation time of about 0.059 ps. The vibrational thermal conductivity of the liquid Cu model slightly decreases with temperature from about 1.1 W/(mK) at 1300 K to about 1 W/(mK) at 1800 K. Near the melting temperature it is about 30% lower than the vibrational thermal conductivity of the f.c.c Cu model. The calculated thermal diffusivity of the liquid Cu model is demonstrated to retain a constant value of about 2.7 Ã 107 m2/s in the studied temperature range, which is about two orders of magnitude higher than the atomic diffusivity in the model at the melting temperature. The vibrational contribution to the total thermal conductivity of liquid Cu is found to slightly decrease with temperature, being estimated as about 0.70.5% in the temperature range of 14001800 K. Furthermore, the applicability of some simple theoretical treatments of vibrational thermal transport in liquid Cu is discussed.

Â© 2015 Taylor & Francis.The thermal resistance of a crystal lattice with a monatomic unit cell due to threephonon scattering processes is investigated in detail theoretically. A general expression for the lattice thermal conductivity is derived from a combined analysis based on: (i) the Boltzmann equation and (ii) data on the heat current autocorrelation function obtained via molecular dynamics simulations in conjunction with the GreenKubo formalism. It is argued that the phonon gas in a monatomic lattice conducts heat as if it consisted of two distinct parts (two 'thermal fluids'), so that the lattice thermal conductivity can be decomposed into contributions from these two parts. The origin of the behaviour of the phonon gas, which is explored in the present work, is due to an intrinsic interplay between Umklapp and normal threephonon scattering processes. New insight into the nature of the lattice thermal conductivity is demonstrated and the results of the present work are in agreement with previous studies in this area.

Â© 2014, ASM International.Tracer diffusivities provide the most fundamental information on diffusion in materials, and are the foundation of robust diffusion databases that enable the use of the Onsager phenomenological formalism with no major assumptions. Compared to traditional radiotracer techniques that utilize radioactive isotopes, the secondary ion mass spectrometry (SIMS)based thinfilm technique for tracer diffusion is based on the use of enriched stable isotopes that can be accurately profiled using SIMS. An overview of the thinfilm method for tracer diffusion studies using stable isotopes is provided. Experimental procedures and techniques for the measurement of tracer diffusion coefficients are presented for pure magnesium, which presents some unique challenges due to the ease of oxidation. The development of a modified ShewmonRhines diffusion capsule for annealing Mg and an ultrahigh vacuum system for sputter deposition of Mg isotopes are discussed. Optimized conditions for accurate SIMS depth profiling in polycrystalline Mg are provided. An automated procedure for correction of heatup and cooldown times during tracer diffusion annealing is discussed. The nonlinear fitting of a SIMS depth profile data using the thinfilm Gaussian solution to obtain the tracer diffusivity along with the background tracer concentration and tracer film thickness is demonstrated. An Arrhenius fit of the Mg selfdiffusion data obtained using the lowtemperature SIMS measurements from this study and the hightemperature radiotracer measurements of Shewmon and Rhines (Trans. AIME 250:10211025, 1954) was found to be a good representation of both types of diffusion data over a broad range of temperatures between 250 and 627Â¿Â°C (523 and 900Â¿K).

Â© 2014 Institute of Materials, Minerals and Mining and ASM International.Hydrogen is expected to become a commonly used energy carrier on the global scale in the near future. However, hydrogen as a fuel is environmentally friendly only when generated from water using renewable energy, such as solar energy. Therefore, intensive research aims to develop a new generation of solar materials, which may be used for the production of hydrogen fuel from water using solar energy. The highly promising candidates for solar energy conversion are photosensitive oxide semiconductors (POSs), particularly the TiO2based semiconductors, which may be used for converting solar energy into the chemical energy required for hydrogen generation from water, as well as water purification (removal of microbial agents and toxic contaminants from water). The present work considers an R&D strategy for developing TiO2 based systems capable of converting solar energy into the chemical energy via water oxidation. The effect of surface versus bulk semiconducting properties on the performance of POSs is considered in terms of partial and total water oxidation. The progress requires modification of the key performancerelated properties (KPPs) in order to enhance the lightinduced reactivity of the POSs with water. The most recent approach in the development of POSs with enhanced performance is deposition of metallic islets of different size and shape in order to induce a plasmonic effect. The development of highperformance POSs can be achieved through a multidisciplinary approach. It is shown that defect disorder has a critical effect on the lightinduced reactivity of POSs and the solar energy conversion. Therefore, defect engineering may be applied in the development of highperformance POSs. This work considers the hurdles in the development of highperformance POSs for specific applications and formulates the key questions that must be addressed to overcome these hurdles. The concepts developed for TiO2may be expanded for other metal oxides.

In this paper, an extended version of the matrix method is derived in order to address diffusion kinetics for the full anisotropic threedimensional h.c.p. structure. It is shown that the diffusion anisotropy can be properly addressed with a model of 13 atomvacancy frequencies which is an extended version of the wellknown 5frequency model for the f.c.c. lattice. Both tracer and phenomenological diffusion coefficients are calculated using this new approach. Extended Monte Carlo simulations are performed in order to crosscheck some of the results of the matrix method. Applications of the proposed model to experimental diffusion data are discussed.

This paper addresses the numerical analysis of the mechanical properties of titania foam intended for use in tissue engineering scaffolds. Special focus is given to a PDLLA coating that has been shown to distinctly increase the mechanical strength of the scaffold. Microcomputed tomography (ÂµCT) data of a real scaffold are obtained and converted into numerical calculation models. Finite element simulations are performed alternately with and without the PDLLA coating. In addition, a strut model containing a single microcrack is analysed. Numerical results indicate that filling the crack with PDLLA significantly increases the strength of the strut by attenuating stress concentrations. Â© 2013 Elsevier Ltd. All rights reserved.

This paper addresses an innovative syntactic foam (SF) formed by countergravity infiltration of a packed bed of lowcost expanded perlite (EP) particles with molten A356 aluminium. The uniform distribution of EP particles in foams causes an even density throughout the height. Due to the low density (~0.18g/cm3) of EP, the average density of these foams is only 1.05g/cm3 which is considerably lower than most studied SFs. Owing to the high porosity of the filler material (~94%), the total porosity of the new foam reaches 61%. Microstructural observations reveal no sign of damage or unintended EP particle infiltration. EP shows a good wettability whilst essentially no reaction occurs at the EPmetal interface. Under compression, EP/A356 syntactic foam shows stressstrain curves consisting of elastic, plateau and densification regions. On account of its consistent plateau stress (average value 30.8MPa), large densification strain (almost 60%), and high energy absorption efficiency (88%) EP/A356 syntactic foam is an effective energy absorber.

This paper addresses the use of the Lattice Monte Carlo method for the thermal characterization of composite materials. An optimized approach that minimizes computational time is presented. The key aspect of the approach is the avoidance of the need to model the local thermal inertia. A combined finite element and Lattice Monte Carlo analysis is conducted on a model composite for a formal verification of the effective thermal diffusivity and conductivity calculated by the optimized Lattice Monte Carlo method. The effective thermal inertia is calculated separately by making use of the energy conservation law. Â© 2014 Elsevier Ltd. All rights reserved.

Â© 2014, Springer Science+Business Media New York.Tissue engineering scaffolds are designed to support tissue selfhealing within physiological environments by promoting the attachment, growth and differentiation of relevant cells. Newly formed tissue must be supplied with sufficient levels of oxygen to prevent necrosis. Oxygen diffusion is the major transport mechanism before vascularization is completed and oxygen is predominantly supplied via blood vessels. The present study compares different designs for scaffolds in the context of their oxygen diffusion ability. In all cases, oxygen diffusion is confined to the scaffold pores that are assumed to be completely occupied by newly formed tissue. The solid phase of the scaffolds acts as diffusion barrier that locally inhibits oxygen diffusion, i.e. no oxygen passes through the scaffold material. As a result, the oxygen diffusivity is determined by the scaffold porosity and pore architecture. Lattice Monte Carlo simulations are performed to compare the normalized oxygen diffusivities in scaffolds obtained by the foam replication (FR) method, robocasting and solÂ¿gel foaming. Scaffolds made by the FR method were found to have the highest oxygen diffusivity due to their high porosity and interconnected pores. These structures enable the best oxygen supply for newly formed tissue among the scaffold types considered according to the present numerical predictions.

Equilibrium atomic configurations and the kinetics of "order order" and surface segregation processes in B2ordering stoichiometric A50 at.%B binary thin films are investigated by means of Semigrand Canonical Monte Carlo (SGCMC) and Kinetic Monte Carlo (KMC) simulations. The (100)oriented films are modeled with an Isingtype Hamiltonian with previously evaluated pairinteraction energy parameters yielding the effect of "tripledefect disordering". The SGCMC simulations provide equilibrium vacancy concentration and atomic configuration in the films with Batom termination of both free surfaces achieved at high temperatures by the generation of an antiphase boundary. Despite strong vacancy surface segregation, the thermodynamic activation energy for their formation inside the films is the same as in the bulk material. KMC simulations implemented with the SGCMCdetermined equilibrium vacancy concentration reveal very slow relaxation of the films towards equilibrium configuration. The Btermination of the (100) free surfaces is produced by Aatom diffusion inwards into the films mediated by vacancies segregating on surfaces. Â© 2014 Elsevier Ltd. All rights reserved.

Â© 2014 Taylor and Francis.The formalism of thermotransport in a binary system is analysed. Focus is put on a detailed consideration of the heat of transport parameter characterizing diffusion driven by a temperature gradient. We introduce the reduced heat of transport parameter, which characterizes part of the interdiffusion flux that is proportional to the temperature gradient. In an isothermal system represents the reduced heat flow (pure heat conduction) consequent upon unit interdiffusion flux. It is demonstrated that is independent of reference frame and is useful in a practical way for direct comparison of simulation and experimental data from different sources obtained in different reference frames. In the case study of the liquid Ni50Al50 alloy, we use equilibrium molecular dynamics simulations in conjunction with the GreenKubo formalism to evaluate the heat transport properties of the model within the temperature range of 15004000 K. Our results predict that in the presence of a temperature gradient Ni tends to diffuse from the cold end to the hot end whilst Al tends to diffuse from the hot end to the cold end.

Â© 2014 Taylor and Francis.In this paper, a new formalism of a combined tracer and interdiffusion experiment for a binary interdiffusion couple is developed. The analysis requires an interdiffusion couple that initially contains a thin layer of tracers of one or both of the constituent elements at the original interface of the couple (sandwich interdiffusion experiment). This type of interdiffusion experiment was first performed in 1958 by J.R. Manning. The theoretical analysis presented in this paper is based on a newly developed phenomenological theory of isotopic interdiffusion combined with the BoltzmannMatano formalism. This new analysis now provides the means to obtain the composition dependent interdiffusion coefficient and tracer diffusion coefficients simultaneously from analysis of the interdiffusion and tracer profiles in a single sandwich interdiffusion experiment. The new analysis is successfully applied to the results of Mannings original sandwich interdiffusion experiment in the AgCd system (six couples in total) and is validated with an independent determination of the Ag and Cd tracer diffusion coefficients by Schoen using the conventional thin film technique. Suggestions for further development of the sandwich interdiffusion experiment and analysis to the case of multicomponent alloys are provided.

This paper addresses the mechanical properties of CorevoÂ® aluminium foam. The effective Young's modulus, Poisson's ratio, and material yield stress are determined. To this end, samples are tested using uniaxial compressive testing. In addition, microcomputed tomography data of the complex material geometry are obtained and converted into finite element calculation models. The numerical analysis further enables the testing of mechanical material anisotropy and plastic deformation within the material's mesostructure. Â© 2013 Elsevier B.V. All rights reserved.

The phononmediated thermal conductivity of f.c.c. Cu is investigated in detail in the temperature range 401300 K. The calculations are performed in the framework of equilibrium molecular dynamics making use of the GreenKubo formalism and one of the most reliable embeddedatom method potentials for Cu. It is found that the temporal decay of the heat current autocorrelation function (HCACF) of the Cu model at low and intermediate temperatures demonstrate a more complex behaviour than the twostage decay observed previously for the f.c.c. Ar model. After the first stage of decay, it demonstrates a peak in the temperature range 40800 K. A decomposition model of the HCACF is introduced. In the framework of that model we demonstrate that a classical description of the phonon thermal transport in the Cu model can be used down to around one quarter of the Debye temperature (about 90 K). Also, we find that above 300 K the thermal conductivity of the Cu model varies with temperature more rapidly than, following an exponent close to 1.4 in agreement with previous calculations on the Ar model. Phonon thermal conductivity of Cu is found to be about one order of magnitude higher than Ar. The phonon contribution to the total thermal conductivity of Cu can be estimated to be about 0.5% at 1300 K and about 10% at 90 K. Â© 2013 Â© 2013 Taylor & Francis.

Â© 2014 Taylor & Francis.An analytical treatment of decomposition of the phonon thermal conductivity of a crystal with a monatomic unit cell is developed on the basis of a twostage decay of the heat current autocorrelation function observed in molecular dynamics simulations. It is demonstrated that the contributions from the acoustic shortand longrange phonon modes to the total phonon thermal conductivity can be presented in the form of simple kinetic formulas, consisting of products of the heat capacity and the average relaxation time of the considered phonon modes as well as the square of the average phonon velocity. On the basis of molecular dynamics calculations of the heat current autocorrelation function, this treatment allows for a selfconsistent numerical evaluation of the aforementioned variables. In addition, the presented analysis allows, within the Debye approximation, for the identification of the temperature range where classical molecular dynamics simulations can be employed for the prediction of phonon thermal transport properties. As a case example, Cu is considered.

Selfdiffusion of component atoms and orderorder relaxations in a B2ordering binary system AB showing a tendency for tripledefect formation were consistently simulated by means of two Monte Carlo techniques. In view of a strict correlation between antisitedefect and vacancy concentrations the Kinetic Monte Carlo (KMC) simulations were implemented with a temperaturedependent vacancy concentration determined by means of SemiGrand Canonical Monte Carlo (SGCMC) simulations. The Ising model of the system was completed with localconfigurationdependent saddlepoint energy parameters related to vacancy mediated atomic jumps. The simulations elucidated the atomistic origin of the experimentally observed low rate of orderorder relaxations in NiAl, as well as reproduced the experimental relation between the activation energies for orderorder kinetics and Ni selfdiffusion in NiAl. Higher value of the deduced activation energy for atomic migration with respect to the effective energy barriers related to individual atomic jumps indicated their high correlation.

This review paper describes primarily recent theoretical calculations with some supporting experimental findings on titania nanotubes. Nanotubes with different types and sizes are discussed in detail in terms of existing theoretical and experimental achievements. Both classical and quantum mechanical simulations are focused on. The properties of these nanotubes have been treated within first principle density functional electronic structure simulation methods. In this paper, we pay particular attention to computational aspects, but when appropriate, relationships with experimental results on titania nanostructures will be mentioned. First, the structural properties of titania nanotubes are reviewed, focusing from experimental growth mechanism to possible theoretical stable structure and orientation. Second, the electronic structure of nanotubes is discussed in terms of band gap modifications of titania and photocatalytic efficiencies in photoelectrochemical devices. Finally, current computational limitations and future directions are described with respect to the performances of nanotube titania based photosensitive devices.

In this paper we make use of a number of simple models for diffusion in B2, L12 and D03 model structures in order to determine the percolation thresholds of the antistructural bridge (ASB) mechanism. The tracer correlation factor, which is calculated in an adaptation to the ordered alloy of Manning's random alloy formalism, is used to determine the percolation thresholds. Monte Carlo computer simulation is used to provide an exact reference. It is shown that in the B2 structure the ASB mechanism requires substantial levels of disorder in order to operate. In the L12 and D03 structures it is possible for the ASB mechanism to be initiated at a certain composition and low level of disorder only to disappear at higher levels of disorder. In the L12 structure a new mechanism was found which closely couples the diffusion of both components and seems to explain certain features of diffusion in Ni3Al and Ni3Ga.

In this paper we present a formalism for diffusion kinetics of impurities in intermetallic compounds taking the common B2 and L12 structures. For the B2 structure, where only intersublattice jumps occur we show that the impurity diffusion coefficient can be related generally to the host atom diffusion coefficients. If the sublattice preference is also known then this reduces further to a simple relation involving the host atom diffusion coefficient of the preferred sublattice. Application is made to impurity diffusion in CuZn. For A3B alloys with the L12 structure where both inter and intrasublattice jumps occur we focus on some likely cases. If the impurity diffuses by intrasublattice jumps (as does A) then its diffusion coefficient can be related easily to the A atom diffusion coefficient. On the other hand if the impurity diffuses by intersublattice jumps (as does B) then the relationships involves both diffusion coefficients. The results are tested by Monte Carlo simulation.

Diffusion via vacancies in a binary b.c.c. ordered alloy was simulated using a Monte Carlo method. Collective correlation factors and the average cosines of the angle between the first jump of a species and the second of the same species (diagonal) or of the other species (offdiagonal) were calculated, the latter for each sublattice as well as in an average sense. The cosine relations are generally not as successful in approximating the correlation factors as compared with the earlier tracer study by Murcli and Zhang. The cosine relations for the diagonal correlation factors are ia reasonable agreement if they are applied to the sublattice components of the correlation factor and the total correlation factor formed as the harmonic mean.
