摘要(Abstract)：

研究了室温单轴压缩时元素Sb含量对Mg-9Al-5Sn-xSb挤压镁合金棒材的力学性能、屈强比和压缩断口形貌等的影响。结果表明:添加元素Sb可以明显改善挤压态Mg-9Al-5Sn镁合金棒材的压缩力学性能。随着元素Sb含量的增加,挤压态Mg-9Al-5Sn-xSb镁合金压缩性能逐渐增强,当元素Sb添加量为1.5 mass%时,合金的压缩性能最好,其极限抗压强度、抗压屈服强度和压缩伸长率分别为528 MPa、307 MPa和11.0%;随着元素Sb含量的增加,合金的屈强比出现先增大后减小的趋势,当元素Sb添加量为0.6 mass%时,屈强比达到最大值0.66,随着元素Sb含量的继续增加,屈强比又呈现减小的趋势。

关键词(KeyWords)： 镁合金;挤压;锑;压缩;屈强比
