Experimental Investigation of AA2024 Reinforced with Titanium Silicon Carbide and Fly Ash using Ultrasonic Stir Casting
Main Article Content
Abstract
Aluminum is a commonly utilized material in numerous industrial applications because of its outstanding characteristics, including corrosion resistance, lightweight nature and strong thermal conductivity. The Ultrasonic stir casting method (USCM) is a highly efficient process for creating metal matrix composites, which blend the qualities of both the metal matrix and the reinforcement. The present research work focuses on producing aluminum matrix composites through the USCM. A mixture of Titanium (Ti), Silicon (Si) and Carbide (C) in a ratio of 3:1:2 is used as a single reinforcement material, in conjunction with a set percentage of fly ash as part of the reinforcement. All the reinforcements added to the aluminum are in nano-sized particles, ranging from 50 nm to 100 nm. The percentage variations include 3%, 6% and 9% of Ti, Si and C, along with 6% of fly ash in the composite material. The effects of the reinforcements on the microstructure, mechanical and lubrication characteristics were studied in the investigation. Hardness, tensile strength, compressive strength and wear resistance are all considerably improved in the composite that incorporates AA2024 reinforcement compared to the component without reinforcement.
