Refractory tungsten-based medium- and high-entropy alloys form a promising class of strong, heat- radiation-resistant materials for nuclear applications. Here, we systematically explore the radiation tolerance Mo-Nb-Ta-V-W using molecular dynamics simulations machine-learned interatomic potential. Going from pure W to W-based equiatomic binaries, ternaries, quaternary, quinary alloy, simulate damage accumulation up 0.4–0.8 dpa through cumulative collision cascades. We find that evolution are...
Multi-component thin films and coatings (MCTFCs) with stable structure excellent capability are gradually being applied to more complex extreme environment. In the review paper, we summary recent research progress of MCTFCs build comprehensive datasets from composition, experiment condition, microstructure macro-properties. By searching keywords, than 30,000 relevant articles found, including at least 600 systems involving 73 elements. Statistical analysis shows that researched system is...
The new second-order two-scale (SOTS) finite element algorithm is developed for the dynamic thermo–mechanical coupling problems in axisymmetric and spherical symmetric structures made of composite materials. structure considered periodic both radial axial directions homogeneous circumferential direction. only model presented equivalent compact form derived. Then, cell problems, effective material coefficients homogenized problem are obtained successively by asymptotic expansion temperature...
Summary This study develops a novel multiscale analysis method to predict thermo‐mechanical performance of periodic porous materials with interior surface radiation. In these materials, thermal radiation effect at microscale has an important impact on the macroscopic temperature and stress field, which is our particular interest in this paper. Firstly, asymptotic expansions for computing dynamic coupling problem, considers mutual interaction between displacement are given successively. Then,...
Abstract As an exploratory study for structural deformation and thermodynamic response induced by spacecraft reentry aerodynamic force thermal environment, a finite element algorithm is presented on the basis of classic Fourier heat conductive law to simulate dynamic thermoelasticity coupling performance material. The Newmark method Crank-Nicolson scheme are utilized discretize equation in time domain, respectively, unconditionally stable implicit constructed. Four types finite-element...
The fundamental mechanisms of radiation damage in metal alloys equiatomic composition are great research interest due to the possibility use them as new materials for radiation-hard environments. With W-Ta and W-Mo examples, this study investigates effect two factors, namely difference lattice parameters masses constituent elements, on primary by means atomistic simulations. We compare trends obtained with available embedded atom method (EAM) interatomic potential tabulated Gaussian...
