中文摘要	mg-5y-3nd-0.6zr-xgd (x = 0, 2 and 4 wt.%) alloys were prepared by metal mould casting technique, the structures and mechanical properties were investigated. the alloys were mainly composed of alpha-mg solid solution and beta-phase. with increasing gd content, mg5re phase increased and the grain was refined. the mg-5y-3nd-2gd-0.6zr alloy exhibited highest ultimate tensile strength and mg-5y-3nd-0.6zr alloy showed highest yield strength at room temperature. with increasing amount of gd, the thermal resistance was improved. the mg-5y-3nd-4gd-0.6zr alloy exhibited highest uts and ys at 250 degrees c, they were about 1.27 times higher than those of gd-free alloy, which was mainly attributed to the increase of the beta-phase and mg5re strengthening phase.
