Abstract

Metal matrix composites (MMC’s) consist of a metallic matrix combined with dispersed particulate phases as reinforcement. Aluminium 6061 based metal matrix composite are used in the field of transportation, aviation and manufacturing of electrical equipments. Silicon carbide is used as reinforcement in aluminium matrix to get better functional properties.The stir casting method is employed for composite preparation. SiC of different weight percentage (5%, 7.5%, and 10%) is added as reinforcement to get MMC of variable compositions. The Stir cast producthas got dendritic segregation in the base metal matrix with nonuniformity in chemical composition, known as CORING. To overcome this problem generally homogenize annealing (homogenizing) treatment is given on the cast MMC. The hardness, strength, tensile strength and impact resistance characteristics are analyzed and compared with as-cast specimens.Homogenizing provides uniform chemical composition of the matrix in the microscopic level and improves mechanical properties, especially ductility. In all the characteristic tests 5 trials are performed and the average of three consistent values is considered as result output.
