A Review: Aluminium Metal Matrix Composites

The behavior of the mechanical and tribological characteristics of aluminum metal matrix composites made using various techniques is reviewed in this research. Hybrid composites have demonstrated exceptional performance and versatility. Excellent strength-to-weight ratio, resistance to erosion and wear, and relatively low cost are the benefits of aluminum Metal Matrix Composites (MMCs). Because of their remarkable specific strength and thermal stability, they are used in various industries, including steel production, structural engineering, marine engineering, aerospace, defense, and the automotive sector. Unconventional engineering materials known as Metal Matrix Composites (MMCs) are reinforced with materials that exhibit superior mechanical and tribological properties. The most common types of reinforcement include fly ash, graphite, silicon carbide, TiO2, boron carbide, and particulate alumina. In addition to their reinforcement in various applications, this paper provides an overview of their mechanical characteristics and tribological behavior. The effects of various reinforcements on aluminum composites vary. For instance, boron carbide enhances the tensile strength, electrical conductivity, thermal conductivity, and elastic modulus because of its lubricating properties. The inclusion of aluminum oxide produces favorable tribological behavior. Using fly ash improves the mechanical characteristics overall, yield, and tensile strengths. The Al composites are also affected differently by other reinforcements.
