Research Progress of Friction Stir Additive Manufacturing Technology
Friction stir additive manufacturing(FSAM)is a new solid phase additive process.It has high additive efficiency,a wide range of materials,fine comprehensive performance and low cost,so on.FSAM methods can be roughly divided into superimposed plate additive-manufacturing,friction stir deposition additive manufacturing and consumable friction-stir tool additive manufacturing.The basic principle of the FSAM,the microstructure evolution and mechanical properties of the deposit layer were introduced.Finally,the further application of friction stir additive manufacturing was presented.
