EVALUATION OF MECHANICAL PROPERTIES OF ALUMINIUM ALLOY 6061 TITANIUMOXIDE, GRAPHITE AND CHROMIUM HYBRID METAL MATRIX COMPOSITES

Aluminium Metal Matrix Composites (AMMCs) are gaining wide spread acceptance for automobile, aerospace, railway and marine application because of their low density, high strength and good structural rigidity. The objective of this work is to be fabricating hybrid composites with the base metal as Al 6061 aluminum alloy reinforced with different alloying elements of titanium oxide, graphite and chromium. Al 6061 which has better wear resistance and high strength and titanium oxide which has excellent hardness and fracture and toughness are added reinforcement Here the fabrication is done by stir casting. Which involves mixing they require quantities of additives into stirred molten alumina. The prepared specimen is heated at different temperature and Mechanical properties aluminum composite of are evaluated and their suitability is find for various application. The Scanning Electron Micrographs (SEM) of the tested sample indicated uniform distribution of the reinforcement’s particles in the matrix without any voids.
