Abstract

Aluminium hybrid composites are a new generation of metal matrix composites that have the potentials of satisfying the recent demands of advanced engineering applications. These demands are met due to improved mechanical properties, amenability to conventional processing technique and possibility of reducing production cost of aluminium hybrid composites. Present work is investigating the effects of adding SiC and Graphite particulates to Al-4.5% Cu alloy in the mechanical properties of the composites.The Al-4.5% Cu alloy reinforced with 6 wt. % SiC and 6 wt. % of Graphite particulates composites were fabricated by stir casting method. Microstructure and mechanical properties such as hardness and ultimate tensile strength, yield strength were examined. Microstructure of the samples has been investigated by using optical microscope to know the uniform distribution of reinforcement particulates in the matrix. It was abserved that the hardness, ultimate tensile strength and yielding strength of the Al-4.5% Cu alloy increased with the addition of 6 wt. % of SiC and Graphite particulates.
