Other AbstractFriction stir welding(FSW) is a relatively new solid-state joining process, which is an energy efficient, environment friendly and versatile joining technique. Therefore it has been widely used in aerospace, marine, railway, automobile and other industrial fields. In order to realize the light weight of the vehicle, the research on the FSW of dissimilar Al alloy and steel has been paid more and more attention. In this review article, the current state of understanding and development on the FSW of Al alloy and steel are discussed. Particular emphasis was given to three aspects: the FSW parameters, microstructural evolution and mechanical properties. It is demonstrated that high-quality FSW joints of butt, lap and spot welding types can be obtained by controlling the formation of the intermetallic compounds on the Al-Fe interface, and the tensile strength is comparable to the Al base metal under optimized FSW parameters, however, further study is still needed to investigate the accurate microstructure of the Al-Fe interface and the mechanical behavior under complex stress state. At the same time, the further research and development direction in FSW of Al and steel are suggested.
