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…
Machine-learned accelerated discovery of oxidation-resistant NiCoCrAl high-entropy alloys
Dennis Boakye, Chuang Deng
The development of oxidation-resistant high-entropy alloy (HEA) bond coats is restricted by the limited understanding of how multi-principal element interactions govern scale forma…
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…
