Mechanical Behaviour Analysis of Al6061, Al-SiC and Al-SiC-Gr Metal Matrix Composites

This study reflects on the the potential use of aluminium metal matrix composite with reference to the aerospace and automobile industries. The desired mechanical properties are initially identified. Then this study explores the importance and limitations of pure Al6061. In order to overcome these limitations metal matrix composites were preferred as a replacement of aluminium. Aim of this paper is to study about the increase in mechanical properties of metal Matrix composite when compared to its pure material. Here Al6061 is composited with silicon carbide and combination of silicon carbide and graphite as Al-SiC and Al-SiC-Gr respectively. Here composition of Al-SiC is 90% of Al and 10% of SiC. Composition of Al-SiC-Gr is 90% of Al, 7.5% of SiC and 2.5% of Gr. Metal matrix of aluminium is manufactured by Sir casting. Tests like hardness, tensile and charpy impact are used in analysis of mechanical behaviour.
