Research on Damping Capacity of Mg-Li-Al Alloys

WT5BZ]The damping capacity of MgLi4Al and MgLi8Al alloys was studied The results showed that the damping capacity of Mg Li Al alloys increases with the temperature and lithium content For MgLi8Al alloy as an example, the damping capacity go up to Q 1 = 0 01, in the range of high damping metallic materials The higher damping capacity of MgLi8Al alloy may be attributed to the interface damping between α(Mg) and β(Li) phases
