Synthesis And Testing of AA2014-Al2O3(alpha) Nano Composite Abstract—Al2O3 reinforced Aluminium Matrix Composites give advanced mechanical physical properties. They have voluminous applications in automobile, aerospace, defense, sports, electronics, bio-medical and other industrial fields. Various manufacturing techniques like stir casting, ultra-sonic assisted casting, compo-casting, powder metallurgy, liquid infiltration are used for the production of the aluminium matrix composites. These composites reveal advanced physical and mechanical properties like lower density, low coefficient of thermal expansion, good corrosion resistance, high tensile strength, high stiffness, high hardness and wear resistance. Our paper reviews the characterization of mechanical properties like tensile strength, hardness with production route of casting for aluminium matrix- Al2O3 composites. Al2O3 agglomeration along with the increasing volume percentage is still a challenging task in composites materials manufacturing. 0.5% by weight of pure magnesium powder is used as wetting agent. Process parameters are optimized for the stir casting process of aluminium composite. Tensile and hardness test microstructure study was performed to find the deviation from the aluminium alloy. Keywords: Agglomeration, stir casting, aluminium composite. I. INTRODUCTION The use of Aluminium alloys in aerospace and automobile industries are remarkable due to their low density and good mechanical properties.
