A Novel Interpretation on Recrystallization Texture Emergence from Cold Rolled <111>//ND BCC Single Crystals

摘要

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 found 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 texture of cold rolled {111 }<110> single crystal is 18 degrees rotated around these <112> axes from cold rolled matrix orientation and deviates 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 polycrystalline material may also be explained by the same <112> rotation, not by conventional ND//<111> rotation.
