In the present study, Al6082 hybrid composites with multiple reinforcements B4Cand Al2SiO5 was fabricated using stir casting technique. The effect of processing parameters such as stirring speed and stirring time along with varying B4Ccontent (4%to 12%) on mechanical properties such as hardness, tensile and impact strength was studied. The tests were performed based on Taguchi’s L9 orthogonal array followed by analysis of results by analysis of variance (ANOVA). The microstructure and fracture surface of hybrid composites after impact and tensile were studied using scanning electron microscope (SEM). It was found that the dispersion of multiple reinforcements were uniform throughout the matrix along with good interfacial bonding. The mechanical properties were found to increase with the increase in B4Ccontent of up to 8%. The analysis results showed reinforcement content as the most influential parameter followed by stirring time and stirring speed.
