Research Progress in Strengthening of Ultralight Body-centered Cubic(BCC)Structured Mg-Li Alloys
Mg-Li alloy has a broad application prospect in aerospace,thin labtop and other fields due to its excellent properties such as low density,high specific strength and stiffness,good formability.With Li addition over 10.3%,the Mg-Li alloy becomes a single-phase body-centered cubic(BCC)structure,which is the lightest low-density material.However,due to the high content of Li,the strength is very low,which limits application in the engineering field.The research progress in strengthening methods and mechanisms of BCC structured Mg-Li alloy at home and abroad was reviewed,and the low formability of nano-precipitated phase after strengthening were emphatically described.Finally,the existing problems were pointed out and the future development direction was prospected.
