Recent Developments in the Fabrication of Metal Matrix Composites by Stir Casting Route: A Review

K Rajendra, MVS Babu, P Govinda Rao and KNS Suman

Combining high specific strength with good corrosion resistance, metal matrix composites (MMCs) are materials that are attractive for a large range of engineering applications. There are several fabrication methods available in manufacturing the MMC materials. According to the type of reinforcement, the fabrication methods can vary considerably. In this review, the relatively low cost stir casting technique is evaluated for use in the production of silicon carbide/Aluminum alloy MMCs. This paper presents the effect of various factors effecting the stir casting process, challenges associated with it and techniques adopted to overcome these challenges.
