Investigation on deformation mechanism and recrystallization behavior of a Mg–Gd–Y–Zn–Mn alloy by hot compression

Solute Redistribution Assisted Dual‐Gradient Structure With Superior Strength–Ductility Balance in Mg–Zn–Gd Alloy

Heterogeneous structures have demonstrated great potential for overcoming the long‐standing strength–ductility trade‐off in metallic materials. In this study, a novel dual‐gradient structure, characterized by gradients in both grain size and precipitate distribution, was successfully constructed in an Mg–2Zn–0.8Gd (w...

A pathway to achieving strength–ductility simultaneous improvement via solute segregation in gradient-structured Mg–Zn–Gd alloy

This study reports a novel dual gradient-structured (GS) Mg–2Zn–0.8Gd (wt.%) alloy fabricated via surface sliding friction and followed by heat treatment. Excellent grain boundary (GB) stability is achieved through the co-segregation of Zn and Gd atoms. The segregated gradient structure produces an excellent strengthen...
