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-5.5Li3Al-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. 相似文献
