CHARACTERIZATION OF FABRICATED STIR CAST AMC COMPOSITES

Metal Matrix Composites (MMC) have been broadly considered as an alternative for the engineering materials due to their tremendous mechanical properties like high strength to weight ratio, wear resistance, high specific modulus, stiffness, damping capacity etc. Metal matrix composites specially aluminium based metal matrix composites (AMC) are getting popular day by day due to their diverse applications such as aerospace, aircrafts, automobile parts, electronic parts, turbine blades, golf clubs etc. Over the years, AMC have several operational, non-operational and functional uses in numerous engineering fields due to their better performance, environmental and economic benefits. AMC have been widely used in transportation industries because of less noise, lower fuel consumption and lower aerial emissions. It is now accepted that in order to empower the AMC substitution for engineering materials and to make it wide spread, there is a fascinating need to redesign the whole engineering system to reduce weight and volume. In this study; AA6082 based aluminium matrix composites (AMCs) are successfully fabricated by adding Si3N4 particulates as reinforcements using stir casting process.
