An Investigation on the Influence of 'Sic- Particulates Reinforcement' On the Mechanical Behaviour of Al 6061/Sic Composites

Abstract

Metal Matrix Composites (MMCs) are advanced materials gaining significant attention due to their versatile applications across aerospace, automotive, nuclear, biotechnology, electronics, and sports equipment industries. These materials are emerging as strong contenders for use as structural components in high-temperature environments. This study analyzed the mechanical properties of aluminum-based MMCs reinforced with Silicon Carbide (SiC) particles. The composites were fabricated using the stir casting technique, with reinforcement levels ranging from 0% to 10% in increments of 2%. The primary goal of this research was to produce particulate-reinforced MMCs and evaluate their Hardness, impact strength, compressive strength, and tensile strength. The results showed that Hardness improved progressively as the SiC content increased from 0% to 10%. Similarly, compressive and tensile strengths also exhibited an upward trend with increasing reinforcement. However, impact strength demonstrated a decreasing pattern as the SiC content increased. Among the tested composites, the 10% SiC-reinforced composite exhibited superior performance in terms of overall mechanical properties. Microstructural analysis revealed an even dispersal of reinforcement, particularly in the composite with 8% SiC content.
