Solid phase additive manufacturing based on friction stir is a new technology for manufacturing of large lightweight alloy components, which has become one of the hot research topics in advanced manufacturing field at home and abroad.The research status of metal solid phase additive manufacturing technology based on friction stir and related process mechanism were analyzed and summarized. The solid phase additive manufacturing technology based on friction stir can be divided into three categories.One is friction stir additive manufacturing(FSAM), which is based on the principle of friction stir lap welding, the plates are stacked layer by layer. Another is additive friction stir deposition(AFSD) technology, which usually uses a hollow tool to conduct AFSD by additive powder or wire through the hollow.The third one is friction surfacing deposition additive manufacturing (FSD-AM) technology, which is based on the principle of friction surfacing by using a rotating consumable bar to deposit materials to form the designed components. The research and application status of solid phase additive manufacturing technology of metal materials based on friction stir were analyzed, and the characteristics, advantages and disadvantages of three kinds of solid phase additive manufacturing technology based on friction stir were compared.Finally, the future research direction of solid phase additive manufacturing technology based on friction stir was proposed, including revealing their process mechanism, integrated controlling of the formation and property of the AM components, modifying the process assisted with second energy, application of new materials and optimization with artificial intelligence, etc.
