![]() The results clarified the dependence of Vs accumulation on the GB character. Researchers investigated the accumulation mechanisms of Vs at Fe GBs, mainly focused on the interaction processes of Vs with different GBs. The horizontal line indicates the GB position. Several V motion trajectories near the GBs drawn from LKMC simulation. ![]() The technology developed in this research can not only distinguish the spatial position dependence of defect properties at GBs, but also simulate the evolution of defects away from the GB region in a coarse-grained manner. If these properties are simply abstracted as a single interaction parameter, a lot of atomic information related to defects would be missed, thereby affecting the accurate prediction of defect evolution on a long time scale. However, the diversity of GB character makes GBs exhibit distinct local structures and defect properties. In previous multiscale simulations, GBs were often abstracted as two-dimensional planes without specific structures, and a series of energetic and kinetic parameters were used to characterize the structural characteristics of GBs. Polycrystalline/Nanocrystalline (PC/NC) Fe was found to exhibit improved radiation resistance. ![]() ![]() The results were published in the Journal of Nuclear Materials. Using this software, research team explored the accumulation and evolution of vacancies at iron (Fe) grain boundaries (GBs). ![]()
