OPTIMIZING MECHANICAL PERFORMANCE: ALUMINUM 7075 AND INCONEL ALLOY 625 HYBRID COMPOSITE WITH NANO-GRAPHENE FABRICATION VIA ULTRASONIC STIR CASTING

Abstract

Due to their intrinsic characteristics, nano hybrid metal matrix composites are widely used in the automotive, aerospace, and marine sectors. The planning of trials by Taguchi method was used to conduct research on nano hybrid metal matrix composite. Predicting the more accurate factors that result in high tensile strength and toughness is the primary goal. With the goal of achieving excellent casting with the fewest possible results, the management of the processing factors was crucial. Investigating the impact of a process component on the necessary characteristics involved the use of an orthogonal array and analysis of variance. Using the Taguchi technique, the best factors are found to give composite materials their optimum mechanical characteristics. The primary goal of this study project is to identify the factors that affect flawless composite casting. The ideal values were found to be toughness 0.5% Nano graphene + 2% Inconel alloy 625, 250 rpm, 600 °C and tensile strength 1.5% Nano graphene + 6% Inconel alloy 625, 450 rpm, 650 °C. It has been determined that the most important element in improving mechanical characteristics is the composition of the reinforcement.
