摘　　要：The effects of two different casting methods on the microstructures and mechanical properties of as-cast and T6-cast states of Mg-10Gd-3Y-0.6Zr alloy were studied by using metal mold casting and squeeze casting.The results show that the microstructure of Mg-10Gd-3Y-0.6Zr alloy is mainly composed ofα-Mg primary phase and Mg 24(Gd,Y)5 eutectic phase.The squeeze cast grains are small with a dendrite like morphology,and the tensile strength of the alloy in T6 state can reach 285 MPa.While the metal grains are coarse,the eutectic phases are distributed in the grain boundary,and the tensile strength of the alloy in T6 state is only 250 MPa.
