For the purpose of investigation the formation mechanism of recrystallization texture, the effects of carbon and its existing state on cold rolled and recrystallization texture were studied in iron-0.02% carbon single crystals. The results obtained are described as follows. In crystals with the initial orientation of (001)[110], fine carbides markedly retarded the recrystallization. In crystals with the initial orientation of (110)[001], the cold rolled textures are {111}<112> and the recrystallization textures are {110}<001> irrespective of the variation in the existing state of carbon. In crystals with the initial orientation of (111)[11^^-0], cold rolled textures are retained in the initial orientation, and recrystallization textures are composed of two orientations {111} and near {110}. The near {110} recrystallization texture was formed by the preferential recrystallization at the region of {112}<111> slip system operated during cold rolling. Solute carbon increased the {110} recrystallization texture and fine carbide suppressed the recrystallization of {100} grains. The formation mechanism of recrystallization textures in low carbon steels was discussed, based on the obtained results.
