Abstract

The growing demand for lightweight materials in modern automotive industries has spurred the development of Aluminum-based metal matrix composites (AMMC). Utilizing the powder metal-lurgy method for fabrication offers a cost-effective alternative to other methods. Composites of Al6061 with varying compositions of 6–18 wt% SiC (8 microns) and 6–18 wt% B4C (10 mi-crons) were prepared to assess their physical and mechanical properties. Scanning Electron Mi-croscope analysis revealed uniform dispersion of SiC and B4C particles within the matrix struc-ture. The study investigated the enhancement in hardness and tensile properties of aluminum metal matrix composite. The influence of SiC and B4C wt% in AMMC was examined, indicating variations in density, hardness, tensile rupture strength, and tensile strength with varying compo-sitions of SiC and B4C in the composite.
