Microstructure and mechanical behavior of the Mg–Mn–Ce magnesium alloy sheets

The microstructural evolution and mechanical behavior of Mg–Mn–Ce magnesium alloy were investigated in the present study. Mg alloy was prepared with metal model casting method and subsequently hot extruded at 703 K with the reduction ratio of 101:1. The grains were dynamically recrystallized after the extrusion process. Moreover, the (0002) pole figure of Mg–Mn–Ce alloy developed a splitting of pronounced basal texture. The mechanical properties were different due to different angles between c-axis and loading direction (0°, 45° and 90°) in the tensile tests. This significantly induces an asymmetry in the yield behavior. The Mg–Mn–Ce alloy exhibits a classical dimple structure as a result of slip accumulation and ductile tear.
