Friction Stir Welding Of SiCp Reinforced Aluminum Matrix Composite And Fluid Simulation

SiCp reinforced Al matrix composites have a lot of good properties such as great rigidity, specific strength, specific module and wearability, and they are widely used in many industries and have a good prospect, but its application is limited by the problems of welding technology. Friction stir welding is a new solid phase joining method, which is invented by The Welding Institute (TWI). Compared with the traditional welding method, FSW has many advantages and it has been applied to many industrial fields. However, the research of the application of FSW is still a significant subject nowadays.In the dissertation, FSW experiments of SiCp reinforced 2024 Aluminum composite have been done. SiC particle, as the reinforced phase in the matrix, has high hardness, so the material of the friction stir tool should has high hardness and good resistance-wear property. GT35 steel-bonded...
