Abstract

There is a massive demand for lightweight, cost-effective and rapidly processed products because of their significant level of excellence in these days. In the present work, the impact of electric stir casting on 7075 based aluminum alloy developed along with Nano Al2O3 with particle dimension (20-30) Nano microns and weight percentages 1.0, 2.0,3.0, 4.0 has been studied. Many researchers revealed the non uniform distribution of Nano particles possessing high porosity in the matrix. Electric stir casting can prevent the troubles integrating with mechanical stir casting. By infusing Al2O3 particulates right into Aluminium alloy, the Aluminium 7075/1 % Wt. Al2O3 is giving place to Nanocomposite. By incorporating 1% Micro magnesium powder improved the wettability of the reinforcement. SEM micrographs reported that the Nano particles were consistently dispersed throughout the matrix and also executed the efficient grain microstructure. The tensile strength, hardness, and impact results of Al7075/1 % Wt. Al2O3Nanocomposites have efficiently increased as compared to the Al7075 base alloy.
