摘要
稀土元素作为微量元素加入铝及其合金中,不仅有细化晶粒的变质作用,还有净化熔体、减少气体含量及氧化夹杂的精炼效果,从而可显著改善和提高铝及其合金的综合性能。讨论了稀土在铝及其合金中的作用机理。论述了稀土在铝及其合金中的应用现状及发展前景。
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 it so as to improve the comprehensive properties of aluminum and aluminum alloys. The mechanism of the effect is discussed. The present applications and future prospects of adding RE in aluminum and aluminum alloys are described.
