Optimization of stirrer speed on mechanical properties of aluminium graphite stir cast

Using a stir casting method and changing the speed of the stirrer, a lubricant-like metal matrix composite is made and tested for its mechanical properties. A stainless steel stirrer is used to thoroughly combine the alloy and graphite. Once the alloy and reinforcement have been combined into a single, red-hot mass, the stirrer is spun at 200 rpm. The molten metal now exits from the bottom of the furnace along the machine's track. To prevent molten solidification along the route, the temperature is kept at 550 °C. The route transports the molt to a die, where the die is broken apart and the mold is removed. To prevent the alloy from clinging to the walls, non-stick paste is applied to the die, furnace, and walkway. The procedure is repeated for stirrer speeds of 400, 600, and 800 rpm, and the best stirrer speed is determined by comparing the mechanical characteristics of each speed. The major goal of this project is to create a metal matrix composite made of Al-Si alloy and graphite that is cast together using the stir casting process by adjusting the stirrer speed. This is designed specifically for casting alloys and reinforcements together as a composite. Then the casted alloys are compared with each other by determining their hardness, compression, wear behavior, tensile strength, and micro structure to optimize the best stirrer speed.
