摘要: 目前对锑在铝硅合金中的变质作用存在着不同的看法。本工作考察了加锑对铝硅合金的结晶过程,共晶硅相形貌的影响,并考察了锑在铝硅合金中的行径,而且与加钠的合金进行了对比。结果指出,加锑使共晶的形态有所改变,并在硅相中发现了Alsb化合物的存在,认为加Sb的作用是在熔体中析出弥散的AlSb晶体做为Si的异晶核。

Abstract: At present there are different points of view for the modifications role of Sb in Al-Si alloys, This paper describes the effect of adding Sb on the crystalline process and topography of eutectic Si and the trail of Sb was studied in this paper. It is also compared with adding Na. The results show that the eutectic state changes after adding Sb and an AlSb compound appears in the Si phases, The role of Sb is to separate dispersed crystals of AlSb from the melt and these dispersed crystals are heterogeneous nucleus of Si.
