, machining, electromagnetic shielding, and shockproof[1-3]. It is well known that the addition of lithium to magnesium can get workable and body-centered cubic alloys. Magnesium-lithium alloys exhibit two... Li content is greater than 10.3%. Due to their ultra-low density, magnesium-lithium (Mg-Li) alloys are attracting much attention, not only in aerospace applications, but also for use in automobiles......
alloy has lower density than the other magnesium alloys. It possesses better deformation property than the other magnesium also[1-2]. Therefore, magnesium-lithium has attracted more and more interests..., processing and applications range of magnesium lithium alloys [J]. Mater Sci Forum, 2000, 350/351: 31-42.

, they possess excellent specific strength and modulus. Among developed magnesium alloy systems, magnesium-lithium based alloys can offer promising properties because of their lowest densities and relatively good workability. Therefore, magnesium-lithium alloys are attractive for structural or secondary structural applications for aerospace, missile and armor applications[1-15]. At present, the mechanical......
