Abstract

Materials are often selected for structural, aerospace and automotive applications because of better mechanical properties. In recent days development of Hybrid Metal Matrix Composites (HMMCs) has gained lot of interest in Materials Science field. In view of this, the present study focuses on the formation of Aluminum-SiC-Titanium dioxide HMMC. It was aimed to evaluate the mechanical and metallurgical properties of Al2014T6 alloy in the presence of silicon carbide, and Titanium dioxide its combinations. Various compositions are added and by using stir casting method HMMCs are fabricated. The properties like tensile strength, elongation, yield strength, hardness and micro structure were determined. In the presence of Silicon Carbide (SiC) and Titanium dioxide (TiO2) [5%SiC + 5%TiO2 , 2.5%SiC+7.5% TiO2and 7.5% SiC+ 2.5% TiO2] with Aluminum, composites were prepared. It was noticed that newly developed HMMCs exhibits better strength, hardness and elongation when compared with metal alloy.
