摘要
大量研究表明,向铝合金中添加微量稀土元素或复合添加微量元素对改善合金组织和性能均会产生积极作用。本文简述了稀土元素Yb及复合添加的Yb与Zr、Cr等微量元素在7xxx系铝合金中的作用,分析它们对合金综合性能的影响,并对稀土元素铝合金的研究方向进行了展望。
Studies have shown that the addition of trace rare earth elements or composite addition of trace elements to aluminum alloys will have a positive effect on improving the structures and properties.In this paper,the mechanism of rare earth elements Yb and the composite addition of Yb with trace elements such as Zr and Cr in 7×××series aluminum alloys is briefly described,and their effects on the comprehensive properties of aluminum alloys are analyzed,and the development of rare earth elements in aluminum alloys is prospected.
