Dislocation Transmission Across Tilt Low-Angle Grain Boundaries in BCC Fe: The Role of Elastic Interactions
Shuai Zhang, Zhishun Chen, Zhuoming Xie +4
Low-angle grain boundaries (LAGBs) are often regarded as penetrable interfaces to dislocation motion, yet recent studies suggest they can also act as strong barriers. The origin of…

Molecular dynamics simulations of interaction between a super edge dislocation and interstitial dislocation loops in irradiated L12-Ni3Al
Cheng Chen, Dongyang Qin, Yiding Wang +2
The study employed MD simulations to investigate the interactions between a <110> super-edge dislocation, consisting of the four Shockley partials, and interstitial dislocation loo…

Modulating dislocation reactions through preferential hydrogen segregation in bcc metals
Jie Hou, Ducheng Peng, Xiang-Shan Kong +4
The interaction between dislocations is fundamental to plastic deformation, work hardening, and defect accumulation. While extensive research has focused on the impact of solutes o…
