Overview

Metal matrix composites (MMCs), such as SiC particle-reinforced aluminum, are renowned for their exceptional strength, hardness, stiffness, and resistance to wear and corrosion. These properties make MMCs suitable for use in aerospace, automotive, electronics, and sporting goods. Addressing material selection based on mechanical properties is essential for optimal performance.This study focuses on the fabrication of Aluminum (Al-6061) MMCs reinforced with SiC (silicon carbide) and graphite particles using induction casting and manual stirring techniques. The MMCs were prepared with varying weight fractions of the reinforcing particles, specifically 4%, 6%, 8%, and 12%. Mechanical tests, including tensile strength and hardness assessments, were conducted to evaluate the properties of the MMCs and the base alloy.The findings indicate that adding SiC to Al-6061 significantly enhances hardness and tensile strength, with optimal improvements observed at approximately 10% weight of SiC and graphite. Beyond this concentration, there is a slight reduction in these mechanical properties.
