Optical microscopy (OM), scanning electronic microscopy (SEM) and X-ray diffraction (XRD) were performed to investigate the influence of homogenization on the microstructures of the Mg-7Gd-5Y-1MM (Ce-rich RE)-0.5Zr magnesium alloy. The results indicated that α-Mg, Mg24(GdY)5 phase, Mg5(GdY) phase and Mg12MM phase coexisted together in as-cast alloy; the microstructures were largely characterized by α-Mg matrix and gray globular or elliptic ball Mg12MM phase, in addition to those with cubic block Mg24(GdY)5 phase after homogenization; the reasonable homogenization regime was maintained at 530 °C for 32 h.
