Hot Deformation Behavior and Mathematical Model of Ti-microalloyed Steel
The dynamic recrystallization behavior of a low carbon steel and Ti microalloyed steel under different deformation conditions was studied by using a Gleeble 3800 thermo/mechanical simulator. The effect of hot deformation parameters on the flow curves was discussed. It is observed that both the peak stress and steady state stress decrease with increasing deformation temperature. The activation energy of deformation is larger than the activation energy associated with the steady state stress. The addition of Ti produces significant solution strengthening and retards the onset of dynamic recrystallization. Using linear regression analysis, the DRX model for the two steels was developed.
