稀土元素对ZK60镁合金组织和性能影响的研究现状

Research Status of Effect of Rare Earth Element on Microstructure and Properties of ZK60 Alloy

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。

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.
