摘　　要：利用真空熔炼法制备了含钕稀土镁合金,研究了钕对Mg-Al合金微观组织和力学性能的影响。结果表明,稀土钕加入Mg-Al合金时,有Al3Nd相生成,显著地细化了α-Mg相基体晶粒,Mg-Al合金的显微硬度从50.6HV增加到137HV。This paper is studies the effect of the neodymium on the microstructure and mechanics performance of the Mg-Al alloys.The alloys were smelted by the vacuum furnace.the results of microstructure and XRD showed： the grains will be refined and the Al3Nd which has a higher thermal stability will be generate in the alloys when neodymium added,the microhardness of Mg-Al alloy increased greatly from 50.6 to 137HV.
