Mechanical Behaviour of Aluminium based Metal Matrix Composites Reinforced with Aluminium Oxide

Abstract

Aluminium metal matrix composites are one of the new materials used for various applications due to their less cost and light weight. The present study has been done to study the effect of different input parameters namely composition of Al2O3, type of cooling and stirring speed on the micro hardness, and wear rate with conditions i.e. time, sliding distance and load. The effect of various input parameters on output responses have been analyzed using Analysis of Variance (ANOVA). Optical microstructure and SEM was done to see the distribution and presence of Al2O3 particles in aluminium alloy. EDS and XRD was completed to analyze the various elements present in different composites. Main effect plot and interaction plot has been used to determine the optimal design for each output response.
