摘　　要：采用稀土变质剂对ZnAl4Cu1G合金进行变质处理,研究了稀土变质对ZnAl4Cu1G合金显微组织及力学性能的影响。结果表明,稀土的加入能够显著细化ZnAl4Cu1G合金的铸态组织,合金的力学性能得到提高,β相晶粒细化及稀土化合物的强化作用是合金力学性能改善的原因。The effect of rare earths modification of ZnAl4Cul G alloy on the microstructure and mechanical proper- ties were studied. The results indicated that the as-cast microstructure of ZnAl4CulG alloy could be refined by adding Re and the tensile properties would be improved. β phase grain refinement and the reinforcement of rare earth compounds were causes for the improvement in mechanical properties of ZnAl4CulG alloy.
