The aluminium based composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries, owing to their improved strength, stiffness and wear resistance properties.
Aluminium oxide as reinforcement is potentially very effective in developing hard, wear resistant composite materials. Now a day's hybrid composites plays vital role in engineering application.
In this present work aluminium oxide and graphite are added as reinforcement particle into A16061 for preparing hybrid composites. The composites are prepared using the liquid metallurgy route, in which 3–9 wt % age of Al2O3 particulates were dispersed in the base Al1606l alloy and hybrid composites was prepared using the liquid metallurgy route in which 3–9 wt.% age of Al2O3 particulates and 2 wt. % age graphite were dispersed in the base Al606l alloy.
The obtained cast composites of Al606l-Al2O3 and hybrid composites Al606l-Al2O3-Gr are subjected to heat treatment process to enhance the mechanical properties such as microstructures studies, hardness, tensile strength and compressive strength.
