The influences of Mn of the recrystallization behavior and the formation of recrystallization texture in Ti-added ultralow-C steels were investigated and compared with that of low-C Al-killed steels. In Ti-added ultralow-C steels, Mn does not influence the recovery, the nucleation and growth rate of recrystallization, or the recrystallization. On the other hand, in low-C Al-killed steel, Mn inhibits the recovery and retards the growth rate of recrystallized grains. Consequently, the development of ND//<111> is impaired, and the intensity of ND//<110> increases after recrystallization. The differences in recrystallization behavior and annealing texture formation between the two kinds of steel were discussed from the viewpoint of the roles of precipitates and solute Mn. It was determined that Mn-C complex is the main reason for these differences.
