Abstract Nanomaterial reinforced friction stir welding (FSW) is an emerging domain, as it delivers a promising method for enhancing joint properties by making composite joints. Composite joints can enhance surface properties like hardness, strength, corrosion resistance, wear resistance, fatigue life, electrical conductance. Over few years many publications have been reported on the application of nanoparticles reinforcement in FSW joints. The present review critically analyses the current status of nanoparticle reinforcement FSW process. Firstly need, type, behaviour, intrinsic properties of nanoparticles used in FSW are discussed. Then, the microstructural examinations of reinforced joints are analysed. Followed by, various properties associated with reinforced joints are presented with the mechanism of the relationship between microstructure and properties. Finally, various methods of deposition of nanoparticle in FSW is discussed. At last prospects of reinforced FSW are explored followed by concluding remarks.
