The transformation of LPSO type in Mg-4Y-2Er-2Zn-0.6Zr and its response to the mechanical properties and damping capacities

The transformation of LPSO type in Mg-4Y-2Er-2Zn-0.6Zr and its response to the mechanical properties and damping capacities

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, an...

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.
