Abstract: Three kinds of ultra-light Mg-Li wrought alloys, Mg-5.5Li-3Al-1Zn-1Ce, Mg-7.0Li-3Al-1Zn-1Ce and Mg-10.5Li-3Al-1Zn-1Ce, were prepared by vacuum induction melting furnace; then the alloys were extruded and rolled. The microstructures and properties of these alloys were studied. The results indicate that the Mg-5.5Li- 3Al-1Zn-1Ce alloy has the highest strength, the Mg-10.5Li-3Al-1Zn-1Ce alloy has maximum elongation, and the Mg-7.0Li-3Al-1Zn-1Ce alloy has good comprehensive performance. Rolling deformation can increase strength further after extrusion deformation.
