Effective Mass of a Migrating Interface
Xinyuan Song, Chuang Deng
Interfaces are ubiquitous in materials and play a central role in microstructural evolution and material properties. Although interface migration has been studied for more than a c…

Intrinsic grain boundary mobility tensor from three-dimensional interface random walk
Xinyuan Song, Chuang Deng
In recent years, studies have demonstrated that the grain boundary (GB) migration is a three-dimensional (3D) process, characterized by a 3D mobility tensor. In this study, we deve…

Disruptive Atomic Jumps Induce Grain Boundary Stagnation
Xinyuan Song, Chuang Deng
Grain growth in polycrystalline materials can be impeded by grain boundary (GB) stagnation. Using atomistic simulations, we observed that during GB migration, the disruptive jumps…
