Abstract
This investigation comprises of the observation of changes in mechanical properties of Aluminium metal matrix when blended with SiC. AluminiumSiC metal matrix composites (MMCs) are prepared with various weight percentage of SiC using powder metallurgy techniques. The investigation are done using nano powders of pure Aluminium and SiC of sizes 10 m & 30 m and blended samples of Al SiC MMCs with 10%; 20% and 30% of SiC are prepared using ball milling process. With blended MMC powders, cylindrical sample pellets are prepared in a mould with 70% compression by volume using an UTM. Compressed semi solid samples of pure Aluminium and SiC blended Aluminium are prepared for the experiment. These compressed samples were sintered at 2500C-3000C temperature in a muffle furnace and cooled in an inert environment. The prepared samples are tested for hardness and compressive strength using Rockwells hardness testing machine and UTM respectively . The results of this investigation show a positive result and the mechanical properties of Al were found improved with addition of SiC composite compared to pure Aluminium. With increase in the volume percentage of SiC in Aluminium the hardness and compressive strength has increased by 10.8 % and 24.6 % respectively.
