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…
Mathematical validation of the Peierls--Nabarro model for edge dislocations
Yuan Gao, Jian-Guo Liu, Tao Luo +1
In this paper, we perform mathematical validation of the Peierls--Nabarro (PN) models, which are multiscale models of dislocations that incorporate the detailed dislocation core st…
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…
