Aluminium matrix composites have received the attention of numerous researchers, because of its attractive properties like high strength, good thermal conductivity and more strength to weight ratio. Application of the conventional welding processes for aluminium matrix composites, facilitates the formation of undesirable phase at the welded region, which limits the wide spread application. The objective of this paper is to review the literatures belonging to the friction stir welding of the composites and explore the challenges associated to maximize joint efficiency. The major contribution of this paper is to study the issue of welding of ex-situ and in-situ composites, various process parameters, properties of joint and post weld heat treatment process to improve the joint efficiency. This literature review provides some research gaps in the friction stir welding of composites.

Friction stir welding (FSW) is established as one of the prominent welding techniques to join aluminium matrix composites (AMCs). It is a solid state welding process, takes place well below the melting temperature of the material, eliminates the detrimental effects of conventional fusion welding process. Although the process is capable to join AMCs, challenges are still open that need to be fulfill to widen its applications. This paper gives the outline of the friction stir welding technique used to join AMCs. Effect of process variables on the microstructure and mechanical properties of the joints, behavior of reinforcing materials during welding, effect of tool profiles on the joint strength are discussed in detail. Few improvements and direction for future research are also proposed.
