Friction stir processing (FSP) was originally developed for aluminium alloys based on the basic principles of friction stir welding (FSW), a solid-state joining process, is an emerging metal working technique that can provide localized modification and control of microstructures in near-surface layers of processed metallic components. The FSP causes intense plastic deformation, material mixing, and thermal exposure, resulting in significant microstructural refinement, densification, and homogeneity of the processed zone. The FSP technique has been successfully used for producing the fine-grained structure and surface composite, modifying the microstructure of materials so FSPed areas are superior in strength and also have superior formability compared to parent material. This processing also helps to convert a heterogeneous microstructure to a more homogeneous and refined microstructure.
In this review paper survey the literature on FSP, the current state of the understanding and development of FSP effect on mechanical properties is addressed. Differences between effect of FSP parameters on different conditions and their result are addressed.
