Abstract

Friction-stir processing (FSP) is an inspirational approach to the enhancement of metal properties through grain refinement, homogenization of second phase particles, elimination of defects like porosity, and surface modification among others. Although predominantly applied to aluminium alloys, the reach of FSP has now extended to a variety of materials including steels and polymers. This review deals with the fundamental understanding of the process and its metallurgical consequences. The focus is on microstructure, parameters required for microstructure control and mechanical properties of FSP zone; and FSP of selected aluminium alloys.
Keywords— Friction-stir processing, Friction-stir welding, microstructure modification, grain refinement, recrystalization, surface modification.
