With increasing demand for producing surface composites, Friction Stir Processing [FSP] can be considered as a method that can be imposed in producing surface composites. In Friction Stir Processing [FSP], the basic principle involved is microstructural modification of the specimen to achieve the required properties. This paper aims to provide a brief knowledge about Friction Stir Process [FSP] and to summarize the previous studies carried out with respect to Friction Stir Processing [FSP] and how it facilitates change in local microstructure of the specimen. In this paper, we talk through various factors such as machine parameter and Tool parameters, and many more (Dimensions of the pin and shoulder), which needed to be considered to perform Friction Stir Processing.
