Shot peening post-treatment was conducted at SUS304 austenite steel bar-plate rotary friction welding joint with fatigue property deterioration from welding flash. along the shotting intensity increasing, non-synchronous deformation of the plate and flash resulted in non-monotonically evolution of local microstructure, residual stresses, and make the fatigue life increased to flash-removed joint level.
