Abstract In body-centered cubic (bcc) metals such as molybdenum, screw dislocations play a significant role in the softening of alloys. The presence solute atoms alloys can effectively alter formation and movement dislocations. this study, we employed first-principles calculations to delve into electronic origins these influences. Initially, constructed single atomic column triple models simulate with atoms. Our investigation revealed that tantalum (Ta) tungsten (W) increase energy...
Red-bed soft rock easily softens and disintegrates when it comes into contact with water, which is the main factor restricting application of as an engineering filler. Therefore, research on influence seawater softening has great significance for in marine engineering. To examine mechanism under conditions, two kinds experiments, well ion inhibition tests softening, were performed pure water results compared. The variation composition, deformation failure characteristics sea cations process...
Vanadium(V)-based alloys have received extensive attention as promising first-wall and blanket candidates for fusion reactors. In the present study, molecular dynamics (MD) simulations been performed to study displacement cascades in V bulk with recoil energy up 80 keV at 300 K. The results indicate that clustering fraction cluster size of vacancies are higher than those interstitials. nucleation, evolution, dislocation loops studied. It's found 1/2 〈1 1 1〉 interstitial vacancy primary ones,...
As a typical representative of red beds, the softening and disintegration sandstone when it encounters water is an important cause initiated engineering disasters. However, research on this kind rock has mainly focused still water–rock interaction. There lack quantitative analysis mechanistic explanation for basic experimental study dynamic interactions. Therefore, based independently developed multifunctional open channel hydraulic test equipment, was used as reference by designing...
High-entropy alloys (HEAs) hold promise as candidate structural materials in future nuclear energy systems. Body-centred cubic V-Ti-Ta-Nb HEAs have received extensive attention due to their excellent mechanical properties. In this work, the Finnis-Sinclair interatomic potential for quaternary has been fitted based on defect properties obtained with density functional theory (DFT) calculations. The new Nb accurately reproduces vacancy formation energy, migration and interstitial energy....
