The primary radiation damage in pure V and TiVTa concentrated solid-solution alloy (CSA) was studied using a molecular dynamics method. We have performed displacement cascade simulations to explore the generation evolution behavior of irradiation defects. results demonstrate that defect accumulation agglomeration CSA are significantly suppressed compared V. peak value Frenkel pairs during collisions is much higher than due lower formation energy point Meanwhile, longer lifetime thermal spike...
The elemental segregation behaviors and interactions between point defects symmetrical tilt grain boundaries (GBs) in TiVTa concentrated solid–solution alloys (CSAs) have been studied through hybrid Monte Carlo/molecular dynamics (MC/MD) simulations. A pure V model, a random CSA with randomly distributed elements, an equilibrated Ti were constructed to investigate the influence of chemical disorder local on defect–GB interactions. For interactions, GBs interact more strongly interstitials...
