The fabrication of surface metal matrix composites (MMC's) is one of the emerging techniques that are used to produce metals with desired mechanical properties like improved strength, hardness and resistance to corrosion and wear by using various surface treatment methods like surface hardening, Friction Stir Welding (FSW) and Friction Stir Processing (FSP). This paper focused on investigating the effects of using FSP with stainless steel powder as a secondary phase particle in the surface treatment or fabrication of the magnesium AZ61 alloy metal matrix composite surface. The microstructural and mechanical properties of the treated magnesium AZ61 alloy were investigated and conclusions were made on whether the use of FSP and stainless steel powder were effective or not.
