Abstract: X-ray diffraction and orientation mapping in EBSD measurement were applied to obtain information of deformation and recrystallization with the emphasis on the cube orientation in hot rolled high purity aluminum plates. It is shown that cube orientations are retained to a large extent during hot rolling. Some deformed cube grains are found to have experienced large extent of recovery according to their Kikuchi band contrasts. The deformed cube-oriented grains in hot rolled plates are in an unfavorite growth condition with respect to their neighboring grain orientations for the subsequent annealing. The reasons for the phenomena observed, as well as the influence of hot rolling process on subsequent cold rolling and final annealing were discussed.
