摘要
The influence of Ce addition on the microstructure and mechanical properties of AM50 magnesium alloy was investigated to improve its mechanical properties.The results show that the addition of Ce to AM50 alloy results in the grain refinement and the mechanical properties of the Ce-modified AM50 at room and elevated temperatures are remarkably improved.AM50 magnesium alloy containing 1% Ce（mass fraction） shows better refinement and mechanical properties compared with the AM50 magnesium alloy with 0.5% Ce and even AM50 alloy without any Ce.
研究添加铈对高压压铸AM50镁合金显微组织和力学性能的影响。结果表明:添加铈能使AM50镁合金晶粒细化,并使其室温和高温力学性能得到显著改善。相对于未添加Ce和添加0.5%Ce(质量分数)的AM50镁合金,添加1%Ce(质量分数)的镁合金的晶粒更细,力学性能更优。
