ABSTRACT
Magnesium (Mg)-Li alloys have attracted great interest in the fields of aerospace applications, automotive, military, electronics, and transportation industries. According to the phase diagram of Mg-Li alloy, the constitutional phase of Mg-Li binary alloys varies from phase to the dual phase until it is a singular phase ß with increasing Li content. The mechanical properties of the hcp a phase Mg-Li alloys are worse compared to the bcc Mg-Li alloys. A molten salt electrolysis process has been developed as another feasible method to prepare Mg-Li alloys. The Mg-Li-X ternary alloys are conventionally prepared by directly mixing the three metallic elements or master alloys. The addition of Al in Mg-Li alloys brings about the improvement of strength and a little increase of density, but it causes a decrease of elongation. LAE442 was the first evaluated Mg-Li-based alloy system concerning the in vitro and in vivo corrosion behavior.
