For heavily cold rolled 3004 aluminum alloy sheets, it is well known that partial annealing followed by light reduction rolling enhances cube texture formation during the subsequent annealing. In order to know a formation mechanism of the cube texture, especially to clarify behavior of cube-oriented grains during the intermediate processing, changes in microstructure, texture and micro-texture were precisely examined using X-ray analysis, SEM and EBSP techniques. As the results, it is concluded that preferential growth of the cube grains that have nucleated during the partial annealing brings about the strong cube texture after the final annealing. Extent of the preferential growth strongly depends upon the condition of the partial annealing. From the results of EBSP image-quality analysis, the preferential growth of the cube grains is attributed to the fact that an increase in residual strain during the light rolling for the cube grains is lesser than that for grains other than cube orientation.
