Friction Stir Processing (FSP) is a latest technology which was initially developed by using the principle of Friction Stir Welding. Various researchers have performed processing on different aluminium alloys. Also, fabrication of aluminium metal matrix composites was performed by many researchers using this method. In this study, the status of FSP on aluminium MMCs is discussed. FSP has great influence on the surface microstructure, mechanical, tribological and corrosion properties of aluminium MMC. Also, effects of many input parameters such as rotational speed, translation speed, tilt angle and number of passes are to be observed.
