The structure and phase stability of binary tungsten-vanadium tungsten-tantalum alloys are investigated over a broad range alloy compositions using ab initio cluster expansion methods. characterized by the negative enthalpy mixing across entire composition range. Complex intermetallic compounds predicted calculations as lowest energy structures for both alloys. effect atomic relaxation on is almost negligible in W-V, but substantial W-Ta Canonical Monte Carlo simulations used predicting...
The phase stability of fcc and bcc magnetic binary Fe-Cr, Fe-Ni, Cr-Ni alloys, ternary Fe-Cr-Ni alloys is investigated using a combination density functional theory (DFT), cluster expansion (CE), (MCE) approaches. Energies, moments, volumes more than 500 alloy structures have been evaluated DFT, the predicted most stable configurations are compared with experimental observations. Deviations from Vegard law in resulting nonlinear variation atomic moments as functions composition, observed....
Generalized stacking fault energies of aluminum alloys were calculated using density functional theory. Stacking energy was correlated with the d-electrons number transition metal alloying elements. The tendency to twinning is also modified by presence element in deformation plane. Our results suggest that Al alloys, such elements as Zr, Nb, Y, Mo, Ta, and Hf, are expected exhibit a strong work hardening rate due emission partial dislocations.
We describe a comprehensive ab initio investigation of phase stability and mechanical properties W-Ta W-V alloys, which are candidate materials for fusion power plant applications. The density functional calculations compare enthalpies mixing alternative ordered atomic structures the corresponding to same chemical composition. Combining data with large-scale lattice Monte-Carlo simulations, we predict several low-energy intermetallic compounds that expected dominate alloy microstructures,...
Additive manufacturing (AM) technologies have advanced from rapid prototyping to becoming viable solutions, offering users both design flexibility and mechanical properties that meet ISO/ASTM standards. Powder bed fusion using a laser beam (PBF-LB), popular additive process (aka 3D printing), is used for the cost-effective production of high-quality products medical, aviation, automotive industries. Despite growing variety metallic powder materials available PBF-LB process, there still need...
Generalised stacking fault energies of copper alloys have been calculated using density functional theory. Stacking energy is correlated with the d?electrons number transition metal alloying element. The tendency to twiningis also modified by presence element in deformation plane. results suggest that Cu ?transition such elements as Cr, Mo, W, Mn, Re are expected exhibit great work hardening rate due emission partial dislocations.
Recent experiments identified a new type of stress induced structural transformation allowing to combine high strength, great work hardening and good ductility in multiphase Ti alloys. These properties are achieved through reorientation the α′ martensite plates being specific self accommodating II twin relation, i.e. under applied load one variant reconfigure its twinned configuration with visible motion boundary. This mechanism plastic deformation was never observed before thus, current...
Generalized stacking fault energies of palladium alloys were calculated using the density functional theory. The energy is correlated with valence electron transition metal element. twinning tendency also modified by presence an alloying element in plane deformation. obtained results suggest that Pd –transition elements such as Cr, Mo, W, Mn, Re are expected to exhibit high work hardening rate due emit partial dislocations and mechanical twins, which increased strength ductility.
