Stochastic Continuum Models for High--Entropy Alloys with Short-range Order
Yahong Yang, Luchan Zhang, Yang Xiang
High entropy alloys (HEAs) are a class of novel materials that exhibit superb engineering properties. It has been demonstrated by extensive experiments and first principles/atomist…
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…
Phase field model for self-climb of prismatic dislocation loops by vacancy pipe diffusion
Xiaohua Niu, Yang Xiang, Xiaodong Yan
In this paper, we present a phase field model for the self-climb motion of prismatic dislocation loops via vacancy pipe diffusion driven by elastic interactions. This conserved dyn…
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…
