/A356复合材料是可行的。

Abstract

SiC

/A356 composites with 40% SiC

content was fabricated by semi-solid mechanical stirring method.The density of composites was measured

and the microstructure of the composites prepared was observed.The results indicate that special treated SiC

with 800 mesh can be used to prepare SiC

/A356 composite with more than 40% SiC

content

and the SiC

particles can be distributed uniformly in the matrix alloy.With SiC

content increasing from 41%to 43%

the density of the composites decreases from 2.714g/cm3 to 2.615g/cm3 non-linearly.The particles and the matrix exhibit the satisfied bonding effects without obvious interfacial reaction.It is feasible to use semi-solid stirring method to prepare SiC

/A356 composites with more than 40% SiC

content.
