摘要
Abstract
The primary silicon phase in the hypereutectic Al-Si alloy was refined by phosphorus modification, and various kinds of particles existing in the industrial melt were studied. The results show that there are heterogeneous particles(AlP and SiO2)and complex heterogeneous particles[AlP/SiO2and AlP/(Al2O3+SiO2)] in the melt,which provides the solid phase substrate for the nucleation of the primary silicon phase.In the casting process,the variety of roles by heterogeneous nucleation needs to be taken into account.关键词
