Abstract

Demand increases in a global range of the new brand products at national and International level. The metal matrix Nano composites are highly useful in many applications such as aerospace, automobile, military and various other architectural applications. In my research, I have used three different hybrid compositions, namely Nano Al2O3 (20-30nm), Nano-SiC (50nm) and micro Mg which is usesd 1 Weight %. Magnesium is to improve the wet ability of Al2O3 and SiC particles in the Al matrix. The compositions are carried out simultaneously 1.0, 2.0, 3.0, and 4.0 Weight %. Of Nano Al2O3 and Nano SiC. The cast specimens undergo the tests like heat treatment, micro-structural evaluation, density, and porosity measurements, tensile, hardness, Impact, EDX along with SEM. SEM images expose that the Nano particles, fairly distribute and achieve fine grain microstructure in the matrix. The outcomes reveal the reinforcement of Nano particles in Al 7075 matrix substantially increases the Mechanical properties when compared to base metal
