SiC/Al Composite Prepared by High Energy Ball Milling Method
SiC particle reinforced pure aluminum matrix composite was prepared using high energy ball milling method.The effects of the mass fraction of SiC particles on the mechanical properties of the composite were studied.The results indicate that the hardness,yield strength and tensile strength of the composite increase,but the elongation decreases with the increase of the weight fraction of the SiC particles.The fracture morphology indicates that SiC/Al composite shows both ductile and brittle fracture characteristics,and along with increasing the weight fraction of the SiC particles,and the ductile fracture feature decreases.
