中文摘要:简述了稀土元素在镁合金中的作用,重点介绍了Y、Ce、Er、Nd、Dy、Gd、Yb等稀土元素对ZK60镁合金的晶粒尺寸、第二相化合物、室温力学性能以及高温性能的影响,指出了在ZK60镁合金中添加稀土元素的研究存在的问题与不足,并对其发展方向进行了展望。
英文摘要:The effect of rate earth elements in magnesium alloys, such as Y, Ce, Er, Nd, Dy, Gd, Yb and so on, on the grain size, second phase particles, room-temperature and high-temperature mechanical properties of ZK60 alloy were maiorly introduced. The existing problems on research of ZK60 alloy with rare earth elements were eventually pointed out, and its development direction was prospected.
