Stochastic Peierls-Nabarro Model for Dislocations in High Entropy Alloys
Tianpeng Jiang, Yang Xiang, Luchan Zhang
High entropy alloys (HEAs) are single phase crystals that consist of random solid solutions of multiple elements in approximately equal proportions. This class of novel materials h…
A New Formulation of Coupling and Sliding Motions of Grain Boundaries Based on Dislocation Structure
Luchan Zhang, Yang Xiang
A continuum model of the two dimensional low angle grain boundary motion and the dislocation structure evolution on the grain boundaries has been developed in Ref. [48]. The model…
Grain boundary triple junction dynamics: a continuum disconnection model
Chaozhen Wei, Luchan Zhang, Jian Han +2
The microstructure of polycrystalline materials consists of networks of grain boundaries (GBs) and triple junctions (TJs), along which three GBs meet. The evolution of such microst…
A Continuum Multi-Disconnection-Mode Model for Grain Boundary Migration
Chaozhen Wei, Spencer L. Thomas, Jian Han +2
We study the Grain Boundary (GB) migration based on the underlying disconnection structure and mechanism. Disconnections are line defects that lie solely within a GB and are charac…
Dislocation dynamics formulation for self-climb of dislocation loops by vacancy pipe diffusion
Xiaohua Niu, Yejun Gu, Yang Xiang
It has been shown in experiments that self-climb of prismatic dislocation loops by pipe diffusion plays important roles in their dynamical behaviors, e.g., coarsening of prismatic…
