Segregation-Controlled Diffusion-Induced Grain Boundary Migration in Alloy 690
Yuntian Jiang, Shuai Zhang, Zhuoming Xie +4
Grain boundary (GB) migration accompanied by Cr depletion is widely observed in Alloy 690 and is closely linked to intergranular degradation and stress corrosion cracking. However,…

Atomic-Scale Insights into Solute Drag Effects on Grain Boundary Motion in Mg-Al and Mg-Ca Alloys
Zhishun Chen, Shudong He, Shuai Zhang +8
The slip behavior of dislocations and grain boundaries critically governs recrystallization and plastic deformation in Mg alloys and can be strongly influenced by solutes. However,…

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…
