Development of Vacuum Assisted Stir Casting Technique for the Production of Aluminium Metal Matrix Composites with Enhanced Properties

Summary

This research proposal aims to enhance the production process of aluminium metal matrix composites (AMMCs) by developing a vacuum-assisted stir casting technique. The current stir casting method, while efficient, suffers from issues such as gas entrapment leading to porosity in the final product. By introducing a vacuumizer into the process, gas removal during casting will be facilitated, resulting in improved mechanical properties, reduced defects, and enhanced surface finish. The project will utilize scrap aluminium alloy from various sources as matrix material and incorporate reinforcements such as Al2O3 and SiC. Through comprehensive mechanical, microstructural, thermal, and wear property analyses, the effectiveness of the vacuum-assisted stir casting technique will be evaluated. The research holds significance for automotive component applications and contributes to the sustainable development of aluminium composites.
