Abstract—In this study, a Magnesium based alloy namely AZ91 based hybrid nanocomposite was fabricated using TiC by Friction Stir Processing (FSP). FSP of AZ91 was conducted with particle addition under ambient cooling conditions. Distribution of nano TiC particles in the Mg matrix was studied using Optical Microscope. Grain size analysis of the as-cast and FSP AZ91/(TiC) composite were done using optical microscopy. The performance of the fabricated nanocomposite was investigated using pin on disc wear test on Universal Tribometer using different loads.
