摘要：

Hybrid aluminum matrix composites (HAMCs) reinforced with different amounts of ceramic particulates consisting of silicon carbide (SiC) and graphite (Gr) were developed. The amount of ceramic powder was 5 - 15 mass%. Parameters of the hybrid composites such as microstructure, density, and porosity and mechanical properties such as hardness and tensile strength were analyzed. Scanning-electron-microscope photomicrographs showed a uniform distribution of (SiC + Gr) particles in the Al matrix. The density and porosity of the hybrid composite increased from 2.69 to 2.72 g/cm(3) and from 0.37 to 1.20%, respectively; Vickers hardness and tensile strength, from 49.5 to 85 VHN and from 161.5 to 187 MPa, respectively. The relative elongation decreased from 8.6 for 5.3 as the content of ceramic particulates (SiC + Gr) increased from 0 to 15 mass%.
