Abstract

Because of its superior cold formability, a great amount of IF steels is being produced by many steel manufacturers. Accordingly, numerous efforts have been made to understand the mechanism of improved plastic strain ratio in Ti-added IF steels1“3. Several mechanisms have been proposed to explain the effect of Ti on the deep drawability of these steels: l)the scavenging effect that is removing carbon and nitrogen from the solution by fixing them as stable precipitates, 2)promotion of (111) texture by fine dispersion of TiC precipitates, and 3)effects of substitutional elements in solid solution4. in spite of these advantages, Ti-added ultra low carbon steels have a disadvantage of high recrystallization temperature. Hayakawa et al.5have reported that recrystallization temperature is sharply rises with the increase in titanium content and reaches a peak when solute titanium is nil, and the acute recrystallization temperature is lowered with the decrease in amount of fine TiC precipitates.
