: The present study was aimed at evaluating the effect of hardness and impact strength of Aluminium Alloy(Al2O3) , B4C particulate reinforced Composites. These AMCs with reinforcement are finding increased applications in aerospace, automobile, space, underwater and transportation applications. An effort is made to enhance the Hardness, Density and Impact properties of AMCs by reinforcing Aluminium Alloy matrix with Varying Proportion of small particles of B4C by stir casting method. Aluminum alloy matrix varying proportions of B4C particulates were fabricated. The microstructure, hardness and impact strength properties of the fabricated AMCs were analyzed. The optical microstructure study revealed the homogeneous dispersion of B4C particles in the matrix. Based on the results obtained from the Density, Tensile Strength, Hardness and Impact of the metal matrix composites it is observed that, the Tensile Strength ,hardness and impact strength increases with increase in the amount of reinforcement content.

Al2O3, B4C particulates, Tensile Strength, Impact strength, Hardness strength – property analysis.
