Abstract: The necessity and the importance of the new materials with superior properties in the modern and hi-tech industries have become inevitable. For many industrial applications and particularly in nuclear applications, a wide range of materials is being adopted. The selected materials should have high strength, low density and high hardness with better machinability. The present work is focused on the evaluation of properties of AA (6061) - Al2O3 - Stainless Steel 316 powder composite. The composite is fabricated through Stir casting. The mechanical properties such as hardness, yield strength, tensile strength are determined. The uniform dispersion of the reinforcement particles in the matrix is ensured through scanning electron microscopic image. Tribological properties such as coefficient of friction and wear rate is determined. Influence of Al2O3 and Stainless Steel 316 powder weight percentage is considered for the evaluation in order to identify its influence on mechanical and Tribological properties.
