Abstract

A series of cold rolling and annealing experiments were conducted to examine the influence of solute carbon during cold rolling on the annealing texture. Hot band samples with grain sizes of 8 and 47 µm were used and rolling was carried out to reductions of 70% and 85%. Two levels of solute carbon were obtained prior to cold rolling by quenching and overaging. Recrystallization textures were measured following single and two step isothermal annealing treatments. In the latter, the level of solute carbon is lowered prior to the commencement of recrystallization. For the single step treatment, the {111} texture intensity was lower in all the samples that had a high level of solute carbon present during rolling. However, when the two step annealing treatment was employed a different trend emerged. Under these circumstances, the fine grain size high rolling reduction sample showed a stronger {111} texture after annealing when the solute carbon level was high during rolling.
