Relaxation Curves

The effect of carbo-nitride precipitation on the recrystallization behavior of Ti-stabilized extra low carbon steels was investigated. The precipitation behavior of titanium carbo-nitride was analyzed using transmission electron microscopy (TEM), a chemical extraction method, and the small angle neutron scattering (SANS) method. The recrystallization temperature was varied from 590°C to 680°C depending on the alloy chemistry and hot rolling process. The total amount of precipitates in the hot bands did not significantly affect the recrystallization temperature of the alloys. Isothermal annealing treatment showed a plateau in the stress relaxation curves, i.e. a delay in the recovery, when precipitation occurred during the annealing treatment. A model developed to explain the dynamic interaction of the precipitation with the recovery in the microalloyed austenite was successfully adopted to simulate the delay of the recovery during the recrystallization treatment of the cold rolled Ti-stabilized extra low carbon steels.

Scavenging Effect

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.
