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.軽金属学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/75348https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75348/1/J.%20Jpn%20Inst.%20Light%20Metal%2051%282%29%20119.pdf0451-59941880-8018AN00069773軽金属5121191242001-02jpninfo:doi/10.2464/jilm.51.119publisher
