The present study deals with the investigation of effect of reinforcement (Zirconium dioxide) particles on mechanical properties of aluminium alloy (Al6061) composites, fabricated by stir casting method. The MMC’s specimens were prepared by varying weight fraction of the reinforced particles as 0 Wt.%, 2.5 Wt.%, 5 Wt.%, and 7.5 Wt.% and keeping all other parameters constant. The microstructure and mechanical properties of fabricated MMC’s were analysed. Microstructural studies of the MMC’s reveal a uniform distribution of zirconium dioxide (ZrO2) particles in the Al6061 matrix. The mechanical properties like hardness, tensile strength and impact strength were improved with the increase in weight fraction of zirconium dioxide particles in the aluminium matrix. It was observed that the elongation decrease with increase weight fraction of zirconium dioxide particles in the aluminium matrix.
