Abstract
This study investigated the properties of aluminum alloy composites reinforced with nano-SiC particles produced by stir casting and hot rolling at a temperature of 5500C. Microstructural analysis reveals that nano SiC particles are uniformly distributed with good bonding to the alloy Al6063. The nano SiC particles align in a rolling direction, and the volume phase was analysed as per ASTM standards. It was observed that due to grain refinement the porosity was reduced due to the inclusion of nano Sic. The tensile strength and hardness of synthesised hot rolled composites significantly increased owing to enhancement of grain refinement and reduction in porosity.
