目前国内外对于高性能铝硅合金的两大研究方向,一是低硅铝合金(Si≤1%),尽量降低Al-si基体合金中杂质含量,最大限度提高合金导电性能;二是高硅铝合金(Si≥30%),尽可能提高硅在铝合金中的过饱和度,此类高性能铝合金侧重提高材料的电热稳定性、耐摩擦性等力学性能.本文总结了国内外对于高硅铝合金的研究进展,提出通过添加稀土元素优化合金成分和采用先进制备技术等方法,以期获得高性能硅铝合金.
There are two main research ways of high performance AI-Si alloy in the world. One is to decrease silicon content (Si≤1%) and other impurity elements content in order to obtain the high conductivity. The other main work is to increase silicon content(Si≥30%). By increasing the maximum saturation of silicon in aluminum extremely, these AI-Si alloys have great hardness and great electrothermal stability. The research progress in the world is pres-ented, and a new kind of A1-Si alloy by adding some special RE elements and by advanced processing way, which posses high conductivity, high strength and high electrothermal stability, is proposed.
