Abstract
In this research, a 4-Layered functionally graded Aluminium metal matrix composite (FG AMMC) is synthesized through the powder metallurgy route. Each layer is fabricated with a predetermined composition, with varying percentages of pure aluminium and silicon carbide. The material is tested for density, hardness and compressive strength. The microstructural analysis is carried out through SEM, XRD and EDAX. The density of the material increases with increased concentration of reinforcement. The top layer with 7.5% SiC shows a high microhardness value of 146 HV. The FG AMMC exhibited higher hardness than similar materials and composites reported in literature. The compressive strength of the FG AMMC is found to be 160 MPa. The Microstructure shows better bonding between the particles, lesser microcracks and micropores. The distribution of reinforcements is found to be uniform, and this FG AMMC is recommended for applications like Gears and Driveshafts.
