摘      要：*** Magnesium alloys containing rare earth elements(Mg-RE al-loys)are attractive structural materials for aerospace,defense,and automotive industries due to their relatively high strength,low density,and good castability[1-4].For casting Mg-RE alloys such as Mg-Nd,Mg-Gd,and Mg-Gd-Y,their high performance is mainly ascribed to a significant precipitation strengthening[5-7].
