Manufacture and Properties of SiC(p)/AI Composites Made by Squeeze Casting

摘要

SiC(p)/Al composites(volume fraction of SiC V_f=30～40％)were manufactured successfully bysqueeze casting,and its properties were investigated.The reinforcements distributed homogeneously andbonded tightly with the matrix in the material.Compared with the matrix alloy Grade 6061,the elasticmodulus of SiC(p)/6061 composite is increased by 1.17 times,the tensile strength increased by 27％,whilethe coefficient of thermal expansion is decreased by 51％.
