Investigation on mechanical and tribological properties of Al 7175 matrix composite with graphite and fly ash

Metal matrix composites (MMCs) have been noted to offer such tailored property combinations required in a wide range of engineering applications Aluminum metal matrix composites (AMMCs) are potential materials for various applications due to their good physical and mechanical properties. The addition of reinforcements into the metallic matrix improves the stiffness, specific strength, wear, creep and fatigue properties compared to the conventional engineering materials.The aim involved in designing aluminum based metal matrix composite by combining different percentage of particulates in the combination. Current investigation is concentrated on the fabrication of aluminum 7175 based metal matrix composites reinforced with Graphite & Fly ash by crucible casting technique to determine Wear resistance, Hardness, Tensile strength various volume-based ratio.
