【 摘 要 】
In the present research, a Mg–4Zn–1.2Y–0.8Nd (wt.%) alloy was heat treated and hot extruded with different passes. XRD, SEM, TEM and tensile testing were employed to characterize the microstructure evolution and mechanical properties. The results exhibited that the semi-continuously distributed W-Mg3Zn3Y2 phases formed the skeleton structure which separated the α-Mg matrix into a dual-size grain structure. In addition, the Mg24Y5, Mg41Nd5 and Y2O3 phase was also observed in the heat-treated alloy. Moreover, it was found that the Mg24Y5 phase had an orientation relationship with the α-Mg matrix of
