摘要：

Through-thickness texture gradient in AA 7055 aluminum alloy rolled plate has been investigated using the electron back-scattered diffraction (EBSD) technique. Quantitative analyses of texture in five layers from the surface to the center of the plate were performed. A pronounced texture variation through the plate thickness was found. In the center layer, a typical beta fiber texture running from {112} (111) orientation through {123} (634) orientation to {011} (211) orientation was found. Near the surface, in contrast, shear type textures including {001} (110) orientation, {112} (110) orientation and {111} (110) orientation were dominating. In particularly, when the shear type textures reached the maximum in both intensity and content, the beta fiber became minimums. (c) 2007 Elsevier B.V. All rights reserved.
