Abstract

In this study, to clarify the formation process for electrolytic capacitor, crystal orientations and residual strains in a cold rolled foil, a partially annealed foil and an additionally rolled foil were evaluated by EBSP method. The partially annealed foil and the additionally rolled foil were heat treated at 300°C and the crystal orientation and the grain boundary character were analyzed. The main results are summarized as follows. (1) Additional rolling preferentially introduces strains in off-cube grains. (2) Most of the grain boundaries of cube grains are high angle boundaries. (3) The cube grains in high purity aluminum foils grow by the migration of high angle boundaries due to the lower strain energy.
