Mg-1.5 mass%Zn-0.2 mass%Ce alloy was hot-rolled at 723 K and its tensile properties and stretch formability were investigated by conducting tensile and Erichsen tests at room temperature. The rolled Mg-Zn-Ce alloy exhibits greater balance of tensile elongation and stretch formability than the commercial Mg alloy, and the balance almost corresponds to that of typical structural Al alloys. This may be attributed to a texture modification, resulting from a synergistic effect of Ce addition and high temperature rolling.
