Abstract
Recovery and recrystallization behavior of the Ti added low carbon steel sheets (0.0096mass%C–0.097mass%Ti) with two different states of carbon atoms were investigated. States of carbon atoms in the hot rolled sheets were characterized by 3-dimensional atom probe (3D-AP) analysis. The recovery was delayed in the sample containing solute carbon. It is considered that this delay arised from the existence of C–Mn or C–Ti dipole. After 85% cold rolling and annealing at 800°C, the specimen without solute carbon showed {111}‹112› recrystallization texture and polygonal ferrite. In contrast, the specimen contained solute carbon showed {111}‹110› recrystallization texture and pancake shaped ferrite microstructure. It is considered that the difference of recovery behavior affects development of the recrystallization texture.
