Abstract

Composite materials are created by combining two or more different materials, which results in new material with enhanced properties when compared to the original components. In the case of Metal Matrix Composites (MMC), the main component is metal, while the reinforcement is made up of ceramics. MMCs are popular due to their durability and toughness, while ceramics provide high elastic modulus. They are widely used in various industries such as sports, automotive, aerospace, packaging and heavy industries. Aluminum-based composites are particularly favored in production due to their low density, high fatigue strength, and excellent resistance to corrosion (Tu et al., 2002). The objective is to produce a distinct aluminum-based composite, containing 2% of aluminum oxide (Al2O3), and then evaluate the mechanical and microstructural characteristics in comparison to pure aluminum using powder metallurgy.

Introduction

Metal Matrix Composites (MMC) have been utilized across numerous industries for many years. These composites offer excellent high-temperature capabilities, thanks to their high thermal conductivity, strength-to-density ratio, stiffness and thermal conductivity (Chawla and Chawla, 2006). Currently, Aluminum Matrix Composites (AMC) have numerous engineering applications. The advancements in AMCs have prompted various industries to favor aluminum (Al)-based composites over Al alloys and pure Al because of their superior properties such as high thermal conductivity, strength-to-density ratio, stiffness and high thermal conductivity (Figure 1). They possess great high-temperature capabilities in comparison to their alloys (Tu et al., 2002 and
