Summary

The magnesium-lithium system is of both theoretical and technical interest. From the equilibrium diagram given in [1], it can be seen that magnesium-lithium alloys exhibit two phase structures, the α (hcp) up to 5 wt.% Li and β (bcc) above 11 wt.% Li. Between 5 and 11 wt% Li alloys are composed of two phases α and β. The α phase exhibits a moderate strength and low formability, β phase has better ductility, but a lower creep resistance. The two phase structure (α and β) shows an interesting compromise in properties because they combine the moderate strength of the α phase and an excellent ductility of the β phase. A superplastic behavior of the two-phase alloys has been reported, too [2].
