フェライト鋼の{111}再結晶集合組織生成機構の一考察

概要

論文の詳細を見る
Recrystallized ND⫽<111> texture is obtained from cold rolled ND⫽<111> matrix even in single crystals where no grain boundary exists. These ND⫽<111> recrystallized grains are analyzed to emerge by <112> rotation from cold rolled ND⫽<111> matrix. This rotation is related to {110}<111> slip systems operated during cold rolling. Recrystallized orientations from cold rolled {111}<110> single crystal are 18 degrees rotated around these <112> axes and deviate from ND⫽<111> by 6 degrees. Since this deviation is not recognizable in polycrystalline material owing to its symmetry, ND⫽<111> recrystallized texture in cold rolled commercial ferritic steels such as IF steels or electrical steels, may also be explained by the same <112> rotation, not by conventional ND⫽<111> rotation.
