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…

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…
