N2 - The texture of different burnished subsurface layers of 2024 aluminum alloy was characterized by EBSD. The burnished subsurface was subdivided into four layers: surface layer, near surface layer, near bulk layer and bulk layer. It was found that the initial Brass component rotated towards R-Bs {110} <223> component along the α-fiber at the low strain induced by FY and FZ force. The shear strain induced by friction force between the burnishing tool and the specimen surface was so large that almost all the β-fiber texture rotated around the X axis of the cylinder specimen to shear textures including {023} <233> orientation, R-cube {014} <104> orientation and {112} <110> orientation. It was found that a texture gradient, shear texture in surface layer and rolling texture in other layers, was produced in the burnished subsurface. The whole texture intensity was maximal in near surface layer. TEM and RETEM studies also indicated that the nano/ultrafine-structure was produced in the top surface.
