Аннотация
The transformation of LPSO type in Mg-4Y-2Er-2Zn-0.6Zr during heat treatment and its influence on damping and mechanical properties are reported in this work. Prior to heat treatment, the alloy consisted of α-Mg matrix and lamellar 14H LPSO phases. After 510 °C heat treatment, lamellae shortened, and their content decreased. Upon 8 h heat treatment, block 18R LPSO phases formed at the grain boundaries while 14H LPSO lamellae disappeared. Presence of block 18R LPSO phases improved mechanical and damping properties of the alloy. The corresponding mechanisms of the influence of LPSO type and morphology on mechanical and damping capacities are discussed.
