Abstract

Metal matrix composites (MMC’s) have evoked a keen interest for automotive and small engine applications because they have preferable combinations of mechanical characteristics. In recent times, it could be noticed that development of the metal matrix composites (MMC’s) has been emerged as a significant area of research in material science. The reinforcement in metal matrix composites is in the form of continuous or discontinuous fibers, whiskers or particulates, in various weight fractions. Among metal matrix composites, particulate reinforced AMC’s are chosen due to their better mechanical and physical properties. Aluminum metal matrix composites exhibit desirable properties than individual conventional material used alone. The present investigation is aimed at evaluation of mechanical properties of Al 4032 reinforced with nano- SiO2 at different wt% 0, 1, 2, 3 by stir casting method. The
mechanical properties of MMC’s viz., tensile strength, compression strength, impact strength and hardness strength, microstructure were characterized
