This work presents a study of the influence of Ti on the kinetics of static recrystallization measured at different temperatures and on the kinetics of induced precipitation. The recrystallized fraction has been measured using the method known as back extrapolation. It has been found that using this method the softened fraction and the recrystallized fraction are approximately equal. The method used has also made it possible to draw, as will be seen later, precipitation-time-temperature (PTT) diagrams, until now determined in other Nb microalloyed steels using theoretical equations, or using transmission microscopy, and discovering in this way the kinetics of the precipitation induced by the strain. The recrystallized fraction will be modeled in accordance with Avrami's equation, as its application in hot rolling is of great use.
