Abstract

In present study, abnormally coarsened grains in high purity aluminum foil sheets with cube texture ({100} (001)) after a final annealing was analyzed using SEM/EBSP method. Most of abnormally coarsened grains had Goss({110}〈001〉) or S ({123}〈634〉) orientations. The coarsened grains with Goss and S-orientations were surrounded by Σ5 and Σ7 co-incidence boundaries, respectively. It was found that these coincidence boundaries would enhance the abnormal grain growth of Goss and S oriented grains and that these grains would grow using energy of sub-boundaries between cube-oriented grains as the driving force. The distribution of Goss oriented grains in the partially annealed foil sheets was evaluated by SEM/EBSP method. It was clarified that many Goss-oriented grains were distributed in the transition band on the central layer of the sheets.
