摘　　要：本文研究了Zr、RE对Sip/ZA27复合材料的晶粒细化工艺,结果表明:添加适当含量的Zr或RE时,都能使复合材料的晶粒得到一定程度的细化,Zr的晶粒细化能力强于RE,而只有Zr和RE复合添加才能得到细小的等轴晶组织,在添加0.2%Zr+0.8%RE时晶粒尺寸最小,达到60μm左右。The crystal refining of silicon particle （Sip） reinforced ZA27 composites （Sip/ZA27） by Zr and RE has been studied, resulting in that adding proper content of Zr or RE has led refinement to a certain degree; the grain refining ability of Zr was stronger than that of RE though with an addition of Zr and RE combination the fine equiaxial structure could be obtained, reaching a minimum value of grain size about 601.Lm as 0.2%Zr and 0.8%RE added.
