Large plastic deformation treatment on surface and fatigue strengthening mechanism of friction stir welding joints of 7075 aluminum alloy

The gradient grain structure was prepared on the surface of friction stir welding (FSW) joints by means of surface mechanical rolling treatment (SMRT). Electron backscatter diffraction (EBSD) results show that a gradient grain layer with a thickness of about 550 μm is formed on the surface of the sa...
