JMS_V4_N1_RP2 Improvement in Mechanical Property of Aluminium Alloy LM-6 Reinforcement with Silicon Carbide and Boron Carbide Particles Prabhat R. Kumar M.K. Pradhan Journal on Material Science 2347–615X 4 1 26 31 Metal Matrix Composite, Silicon Carbide, Boron Carbide, LM6, Stir Casting Aluminium matrix composites are widely used in various advance industries like aerospace, transportation, defence, marine and auto-mobile, piston cylinder and sports, due to their better corrosion resistance, good mechanical property and high strength to weight ratio. Attention is being paid by researchers towards increasing the mechanical properties, and also to provide the attractive aesthetic appearance of the existing material by adding various reinforcement particles. Hence, in the proposed work, silicon carbide and boron carbide is considered to improve the mechanical properties like Tensile strength, hardness, wear resistance and density of the casted aluminium alloy LM6. Aluminium alloy metal matrix composites are prepared by varying the weight percentage of silicon carbide (5, 5, 7.5) and boron carbide (2, 4, 4) using stir casting technique, which is the simple and economical method. When vortex is generated by the stirrer, on the centre of the liquid matrix in the furnace, 220 mesh of boron carbide and 240 mesh size of silicon carbide particle are added on the matrix. Casted Aluminium metal matrix composite has to be tested to find the various mechanical properties. Brinell hardness tester is used to evaluate the bonding strength between reinforcement and the matrix, with 10 mm diameter of steel ball indenter. Atomic force microscopy is used to know the distribution of reinforcement in the matrix. April - June 2016 Copyright © 2016 i-manager publications.
