摘要(Abstract)：

采用扫描电镜、X射线衍射、透射电镜、显微硬度测试和拉伸试验等研究了热处理方式(固溶、退火和时效)对Mg-2Nd-0.5Zn-0.4Zr-1Y(mass%)合金微观组织和力学性能的影响。结果表明:热处理工艺能够降低Mg-2Nd-0.5Zn-0.4Zr-1Y合金中元素的偏析程度,改善合金的组织均匀性;合金显微组织均主要由α-Mg基体、Mg_(12)Nd和Mg_(24)Y_5组成;铸态合金抗拉强度和伸长率分别为153.4 MPa、15.63%;固溶处理和退火处理后,合金抗拉强度和伸长率均得到提高,固溶态合金为168.5 MPa和16.7%,退火态合金为162.3 MPa和17.7%;时效处理后合金的抗拉强度大幅度提高到207.7 MPa,但伸长率略降低到13.49%;综合考虑合金的组织和力学性能,时效处理合金的性能最优。
