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…
Intrinsic Grain Boundary Shear Coupling Tensor
Xinyuan Song, Liang Yang, Chuang Deng
Grain boundary (GB) migration stands as a linchpin process governing microstructural evolution in polycrystalline materials. Over the past decade, the concept of shear coupling, qu…
Unusual acceleration and size effects in grain boundary migration with shear coupling
Liang Yang, Xinyuan Song, Tingting Yu +2
Grain boundary (GB) migration plays a crucial role in the thermal and mechanical responses of polycrystalline materials, particularly in ultrafine-grained and nano-grained material…
Computing the intrinsic grain boundary mobility tensor
Xinyuan Song, Liang Yang, Chuang Deng
Grain boundary (GB) mobility has been conventionally computed as a single value; however, a recent study has suggested that GB mobility should be expressed as a tensor. In this wor…
Driving force induced transition in thermal behavior of grain boundary migration in Ni
Xinyuan Song, Chuang Deng
Grain boundary (GB) migration exhibits intriguing anti-thermal behavior (or non-Arrhenius behavior), with the temperature and driving force playing crucial roles. Through atomistic…
