Aluminum Matrix Composites (AMCs) are gaining traction in aerospace, automotive,
and marine industries due to their superior mechanical properties. By
integrating hard ceramic particles such as silicon carbide (SiC) and aluminum
oxide (Al₂O₃) into aluminum matrices, these composites exhibit enhanced wear
resistance and strength-to-weight ratios. This study explores the fabrication
and characterization of 6061-T6 aluminum alloy matrix composites, reinforced
individually with SiC and Al₂O₃ particles through the squeeze casting technique.
The research includes a comprehensive analysis of microstructures and mechanical
properties, focusing on compressive strength, Brinell hardness, and tribological
behavior. Findings reveal that SiC and Al₂O₃ reinforcements boost compressive
strength by up to 27% and 47%, respectively, and increase hardness by up to 29%
and 20%, respectively, compared to unreinforced aluminum.
