稀土作为微量元素在铝及铝合金中的添加，不仅可以细化晶粒，而且可以净化熔体，减少熔体中的气体和夹杂物含量，从而提高铝及铝合金的综合性能。论述了稀土在铝及铝合金中的作用机理，阐述了稀土在铝及铝合金中的开发应用现状，展望了稀土铝合金的发展前景。
The addition of rare earths as trace elements in aluminum and aluminum alloys does not only refine the grains but also purifies the melt,reduces the gas and inclusions contents in them so as to improve the comprehensive properties of aluminum and aluminum alloys.The mechanism of RE in aluminum and aluminum alloys was discussed,the current situation of development and application of RE in this area was expounded,and the future development of RE aluminum alloys was prospected.
