Abstract

This research article aims at enhancing the mechanical properties of Al-7075 alloy through the incorporation of silicon carbide and graphite powder using the stir casting process. Diverse weight proportions of reinforcements were employed to fabricate alloy composites, subsequently subject to comprehensive mechanical evaluations encompassing tensile strength, hardness, and impact resistance analyses. The findings elucidate substantial enhancements in mechanical properties following the incorporation of silicon carbide and graphite powder. A thorough microstructural examination utilizing Scanning Electron Microscopy (SEM) highlighted a consistent dispersion of reinforcements within the matrix. These results offer essential insights into the strategic composition optimization for elevated mechanical performance in aluminum-based composites, thus fostering advancements in lightweight, high-strength materials essential for diverse engineering applications
