Review and analysis of the effect of variables on aluminium based surface composite fabricated through friction stir processing method

Friction stir processing (FSP) is a remarkable technique to create metal matrix composites (MMCs). FSP can be used to produce MMCs of different materials like aluminium, copper, magnesium, steel etc. Due to the excellent mechanical properties like higher strength to weight ratio, higher corrosion resistance and lighter weight density brand aluminium as a material of choice for different structural application in different industries like defense, marine, automobile and aircraft. Many researchers have found that the microstructure as well as mechanical properties of aluminium can be altered through reinforcing particles like SiC, TiC, Al2O3, etc. Microstructure, mechanical and wear properties of aluminium base material can also be altered by modifying different variables involved in FSP. This paper is a state of art review of consequences of different variables of FSP on mechanical properties of aluminium metal matrix composites (AMMCs) fabricated through the FSP method. This review article will also provide the future research direction for aluminium as a base metal.
