Abstract

Friction stir processing (FSP) is an advanced metalworking technique derived from friction stir welding (FSW) that enables precise microstructural modification of metallic surfaces. Initially developed for aluminium alloys, FSP utilizes intense plastic deformation, material mixing, and localized heating to enhance mechanical properties, improve uniformity, and increase density in treated regions. This technique has proven effective in refining grain structures, enhancing surface characteristics, and facilitating the in-situ synthesis of composites and intermetallic compounds. This review explores the latest advancements, key insights, and emerging applications of FSP in modern material engineering.
