Characterization of phases in Mg-10Y-5Gd-2Zn-0.5Zr alloy processed by heat treatment

Qudong Wang; Yan Gao; Dongdi Yin; Changjiang Chen

Abstract Characterizations of phases in Mg-10%Y-5%Gd-2%Zn-0.5%Zr (WGZ1052) alloy during heat treatments were investigated by OM, XRD, SEM and EDS. The mechanisms of microstructure evolution were discussed. The results show that, after high temperature heat treatments, the Mg 12 ZnY phases still exist. During solution-treatment at 535 °C, the amount of the long-period stacking order structures decreases. At 545 °C for 20 h and 24 h, there are still remnant Mg 12 ZnY compounds in the Mg matrix, the shape of which does not change and the amount does not decrease obviously.
