Abstract:In this research, aluminium composites were fabricated using two alternative casting methods namely, traditional stir casting and ultrasonic-aided stir casting technique. The aluminium composites were manufactured by reinforcing them with three different concentrations of waste spent catalyst and silicon carbide (0.5, 1.0, and 1.5 wt-%), respectively. The microstructural and mechanical behaviour of aluminium composites synthesised using both methods were studied and compared. The microstructure of the aluminiu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
