Abstract: An attempt has been made in this paper to improve upon the properties attained in cast 2014-based metal matrix composites (MMCs) made with SiC dispersoids through extrusion under optimised conditions. The properties attained have been compared between the cast and extruded MMCs in terms of microstructure, physical, mechanical and sliding wear properties, and improvements attained. Attempts have been made to analyse the obtained results through microscopic investigations on the tested samples.

Keywords: extrusion; MMC; metal matrix composites; 2014 alloys; mechanical properties; sliding wear; worn surfaces; friction; silicon carbide; SiC dispersoids; microstructure.
