In the present work stir casting process was introduced and the commercial A356 aluminium alloy reinforced with RHA/ Al2O3 particulates in equal proportions (1wt%, 2wt%, 3wt%, 4wt% and 5wt%) were used for the present study. A356 alloy belongs to a group of hypoeutectic Al-Si alloys and has wide applications in marine and automotive.RHA/Al2O3 based A356 hybrid composite is a refractory compound that exhibits outstanding features such as high melting point, high wear and corrosion resistance due to T6 heat treatment. After T6 heat treatment, the microstructures of (RHA/ Al2O3) undergo a remarkable change, leading to the improvement of tribological properties of hybrid composites. It was also observed that the density of hybrid composites decreased with increasing particle (RHA/Al2O3) content.

Abstract


In the present work stir casting process was introduced and the commercial A356 aluminium alloy reinforced with RHA/ Al2O3 particulates in equal proportions (1wt%, 2wt%, 3wt%, 4wt% and 5wt%) were used for the present study. A356 alloy belongs to a group of hypoeutectic Al-Si alloys and has wide applications in marine and automotive.RHA/Al2O3 based A356 hybrid composite is a refractory compound that exhibits outstanding features such as high melting point, high wear and corrosion resistance due to T6 heat treatment. After T6 heat treatment, the microstructures of (RHA/ Al2O3) undergo a remarkable change, leading to the improvement of tribological properties of hybrid composites. It was also observed that the density of hybrid composites decreased with increasing particle (RHA/Al2O3) content.
