Abstract

In present study, abnormally coarsened grains in high purity aluminum foils with cube texture ({100}(001)) after a final annealing was investigated 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 coincidence boundaries, respectively. This result clarified that these coincidence boundaries would enhance the abnormal grain growth of Goss and S oriented grains. Grain boundary energy of sub-boundaries between cube-oriented grains provided the driving force for the abnormal grain growth. The distribution of Goss oriented grains in the partially annealed foils was characterized by SEM/EBSP method. This characterization revealed that many Goss-oriented grains were distributed in the transition band on the central layer of the sheets.
