Description
Summary:•Nano SiCp -Al6063 alloy was casted using stir casting method and it was hot rolled.•During rolling, equated grains were formed with an average grain size of 20 µm.•The presence of nSiC particles during the solidification minimized shrinkage effects.•The hardness of Al6063/SiC Composites increased by 32% after hot rolling process. 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.
