Fabrication and Characterization of Silicon Carbide and Aluminum Oxide Reinforced 6061-T6 Aluminum Matrix Composites

<div class="section abstract"><div class="htmlview paragraph">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.</div></div>
