Abstract
Mg–0~1.4wt% Mn–0.4wt% Ce alloys were prepared with metal mold casting method and subsequently hot extruded at 430°C with the extrusion ratio of 101:1. Microstructures and mechanical behaviors of Mg alloys were investigated. The results indicate that the grains of Mg–Mn–Ce alloys were dynamically recrystallized during extrusion. The alloy sheets develop a strong (0002) basal texture, which has a great influence on the mechanical properties and the work hardening. The addition of Mn affects the grain size of the as-cast Mg alloy, leading to an alteration of the texture in the extruded sheets.
