Abstract
In this paper, the softening behavior of higher Nb content X80 pipeline steel was investigated by means of the stress relaxation curve. Deformed above 1050°C, the softening of the steel is fast and controlled by static recrystallization. Although the softening at 1000°C is slower obviously, it was also controlled by static recrystallization, no more than the grain growth rate was declined because of the drag effect of solute Nb . Moreover, the pinning effect of precipitation is more effective to retarding the softening at relatively lower temperature and that can be revealed by the softening curve too.
