Mechanical Behavior of AL 7075 Reinforced with Al O and SIC Nano Particles Fabricated by STIR Casting Method

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 Al O (20- 2 3 30nm), Nano-SiC (50nm) and micro Mg which uses 1 Weight %. Magnesium is to improve the wet ability of Al O and 2 3 SiC particles in the Al matrix. The compositions are carried out simultaneously 1.0, 2.0, 3.0, and 4.0 Weight %. Of Nano Al O and Nano SiC. The cast specimens undergo the tests like heat treatment, micro-structural evaluation, density, and 2 3 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.
