FABRICATION AND CHARACTERISATION OF Al6063 METAL MATRIX NANOCOMPOSITES

Nanotechnology is spreading vastly in the various demanding fields of engineering and medicines like aerospace, defence, automobiles, electronics, materials, chemistry, energy, environment, information & communication, consumer goods and biotechnology. Aluminium alloys are widely used in many applications due to their low density and good mechanical properties, better corrosion and wear resistance, low thermal coefficient of expansion as compared to conventional metals and alloys. The aim involved in designing metal matrix composite materials is to get desirable attributes of both metals and ceramics. In this fabrication and characterization of aluminium Al6063 with reinforcement nano γ-alumina(Al2O3) metal matrix composites produced by stir casting process and various test specimens produced with different wt%(0.5%,1%,2%,3) of reinforcement material. Specimens after casting, ageing process is done for better tensile strength and hardness to find the mechanical properties of specimens are subjected to micro structure analysis, tensile test and hardness test
