通过合金制备、微观分析和力学性能测试等方法

分析了Sn对Mg-Zn-Ca系合金微观组织和力学性能的影响。结果表明

加入Sn后

合金组织得到细化

也会使含Ca相析出。Mg-5Zn-2Ca合金的力学性能随Sn含量的增加呈先升后降趋势。当Sn添加量为1%时抗拉强度和屈服强度达到最大值

分别为158MPa和123MPa

伸长率为6.0%。拉伸断口的SEM形貌分析表明

加入Sn后

合金断裂方式没有明显变化。

Effects of Sn on the microstructure and mechanical properties of Mg-Zn-Ca magnesium alloy were investigated by alloy preparation

microstructure observation and tensile testing. The results show that with Sn addition

microstructure of the alloy is refined

and phase contained Ca is precipitated from the alloy. With increasing in Sn content

the mechanical properties of Mg-5Zn-2Ca magnesium alloy is increased firstly and then decreased. With 1%Sn addition

the tensile strength and yield strength reach 158 MPa and 123 MPa

respectively

and the elongation is 6.0%. With Sn addition

transformation of fracture morphology can not be observed from SEM.
