fracture occurs in the heat affected zone of 6061 aluminum alloy. With the increase of heat input, the fracture angle gradually decreases from 41° to 3°, and the fracture mechanism changes from shear fracture to normal fracture. The distribution of nanoindentation hardness of the FSW joints indicates that the heat affected zone of 6061 aluminum alloy is the weakest area, and the fracture angle......
