Stir casting method is one of the simplest low cost and high production rate technology for producing metal matrix composites. In this study the TiO2 Nano particles are combined with A356 to form a newer Metal Matrix Composite (MMC) which is to be utilised in the aerospace, marine, military and Automotive Applications. 0.5TiO2A, 1TiO2A, 1.5TiO2A and 2TiO2A wt% of TiO2 were reinforced with A356 under 10 minutes holding time and 400 rpm stirring speed. Mechanical tests such as tensile, impact and hardness test were conducted on the new Metal Matrix Composite material specimens. Using optical microscope and SEM the microstructure, surface morphology and composition of the manufactured specimens were studied. EDS analysis is done to study the atomic elemental composition present in the MMC.The XRD analysis displays the variation in XRD Patterns of the Nano composites containing various % weight of Nano TiO2. The mechanical tests reveals that there is a significant enhancement in the properties with respect to the 1.5TiO2A wt% of TiO2 reinforced with A356.
