Abstract: Hybrid materials are important engineering materials due to their outstanding mechanical properties. AA6061 and silicon carbide (SiC) particles and Graphite (Gr) particles were synthesized used stir casting method, which can be used in aircraft and automobile industries to improve the strength and reduce the weight of the components. The major physical parameters like composition ratio, total particle content in%, particle size combination are playing an important role in deciding the mechanical properties. Hot forging involving the shaping of metal to improve strength. Tensile tests were conducted on standard specimens machined from the hot forged sections. The tension test is the most common test for determining the mechanical behavior of materials. The results show that, the reinforcement of the metal matrix with SiC and graphite particulates up to a volume fraction of 10%

Keywords: AA-Aluminium alloys, SiC-silicon carbide, Gr-Graphite, AMC-Aluminium matrix composite.
