A Three-Dimensional Continuum Simulation Method for Grain Boundary Motion Incorporating Dislocation Structure
Xiaoxue Qin, Luchan Zhang, Yang Xiang
We develop a continuum model for the dynamics of grain boundaries in three dimensions that incorporates the motion and reaction of the constituent dislocations. The continuum model…

Continuum Model and Numerical Method for Dislocation Structure and Energy of Grain Boundaries
Xiaoxue Qin, Yejun Gu, Luchan Zhang +1
We present a continuum model to determine the dislocation structure and energy of low angle grain boundaries in three dimensions. The equilibrium dislocation structure is obtained…

Continuum model for dislocation structures of semicoherent interfaces
Luchan Zhang, Xiaoxue Qin, Yang Xiang
In order to relieve the misfitting elastic energy, the hetero-interfaces become semicoherent by forming networks of dislocations. These microscopic structures strongly influence th…
