Abstract

Metal matrix composite (MMC) is a composite material with a dispersed phase in a metallic matrix. In this work, the stir casting process is employed to fabricate aluminium MMC. The process parameters selected for this work are squeeze pressure, squeeze time, die preheating temperature and stirring speed. The optimization of the process parameters are carried out with an objective of the maximization of the tensile strength, compressive strength and hardness. The aluminium scrap particles are used as the matrix material and alumina powder is used as the reinforcing material and it is mixed with this matrix material after preheating the same in the fabrication of the MMC. Regression equation for the responses, ANOVA analysis and grey relational coefficient are analysed and the Grey relational grade is determined by integrating the grey relational coefficient of the response variable and ranking is done. The analysis of variance is performed for the tensile strength, compressive strength and hardness and the R-square value are found to be 92.7%, 94.89% and 98.98% respectivel


Keywords: Metal Matrix Composite, Grey relational grade, Grey relation coefficient, ANOVA, Stircasting
