Fabrication and Mechanical Behaviour Investigation on Aluminium 7075 Boron Carbide and Inconel Alloy 625 Metal Matrix Composite Using Ultra Sonic Stir Casting Method

Abstract

Aluminium metal matrix composites produced using the ultrasonic stir casting method offer important benefits in aerospace and automotive applications. Aluminium composite material utility has recently increased in all engineering sectors due to its high strength, good wear and corrosive resistance. This study was designed to disperse boron carbide and Inconel Alloy 625 reinforced with aluminium 7075. By varying the weight percentages of boron carbide (2wt percent,4wt percent,6wt percent, and 8wt percent) and Inconel alloy 625 (2wt percent,4wt percent,6wt percent, and 8wt percent) for aerospace applications. The scanning electron microscope was used to examine the morphology and distribution of reinforced particles in a synthetic aluminium composite material. It virtually depicts the uniform distribution of reinforcement particles in the base material matrix (Aluminium 7075). To determine the hardness of the hybrid composite material, a Brinell hardness test was performed. It has been discovered that increasing the reinforcement percentage increases the hardness of the synthesised hybrid composites when compared to the aluminium 7075 base matrix material. Mechanical property testing on fabricated composites specimens of various compositions has been carried out.
