Abstract

Abstract: Al-7075/Si3 N2 /ZrO2 hybrid metal matrix composite is developed using stir casting method. The mechanical behaviour of the developed composite is carried out using impact test, tensile test and hardness test as per ASTM standards. The micro structural analysis shows that the grain boundaries is having inter-dendritic network of silicon nitride and zirconium oxide particles and it is distributed uniformly in an aluminium matrix. Furthermore, a considerable increment in the tensile strength, hardness and wear properties of the hybrid composite was observed with increasing the percentage reinforcements of zirconia (2, 4 and 6wt%) in Al-7075/Si3 N4 composite (keeping a constant percentage of Si3 N4 of 8wt%).
