Abstract

Solute atoms and precipitates significantly influence the mechanical properties of Mg alloys. Previous studies have mainly focused on the segregation behaviors of Mg alloys after annealing. In this study, we investigated the segregation behaviors of an Mg-RE alloy under deformation. We found that the enrichment of solute atoms occurred in {10

The segregated solutes and precipitates impeded the twin growth, partially contributing to the formation of small-sized {10

\bar{1}

1} compressive twins. This research indicates the twin boundaries can be strengthened by segregated solutes and precipitates formed under deformation at room temperature.

期刊介绍： The Journal of Magnesium and Alloys serves as a global platform for both theoretical and experimental studies in magnesium science and engineering. It welcomes submissions investigating various scientific and engineering factors impacting the metallurgy, processing, microstructure, properties, and applications of magnesium and alloys. The journal covers all aspects of magnesium and alloy research, including raw materials, alloy casting, extrusion and deformation, corrosion and surface treatment, joining and machining, simulation and modeling, microstructure evolution and mechanical properties, new alloy development, magnesium-based composites, bio-materials and energy materials, applications, and recycling.
