%X In this paper the tensile properties and fracture behaviour of aluminum alloy 2009 reinforced with silicon carbide particulates (SiCp) fabricated via elemental powder metallurgical technique were presented. The results indicate that the strength of 15%SiC/2009Al composite decrease with increasing particulates size, but ductility inversely. When particulates were 1.5μm, the breakage is due to tearing of matrix near interface. The failure of composites with 20μm particulate results from crack of SiCp. When particulates are between above sizes, the failure of composite results from tearing of matrix near interface and crack of SiCp.
