Kinetics of the Static Recrystallization of Austenite in Niobium-Microalloyed Pipe Steels


A method is described for experimentally determining the parameters of a model of the kinetics of static recrystallization. Use of the method ensures a close correlation between calculated and experimental values of the percentage of recrystallized metal (R = 0.97). It is shown that the probability of the occurrence of partial recrystallization between roughing passes must be accounted for in order to evaluate the completeness with which static recrystallization takes place during multipass rolling. It was found that the kinetics of static recrystallization of niobium-microalloyed pipe steels depends on their chemical composition. A convenient software tool, HRRM (Hot Rolling Recrystallization Model), has been created to develop new rough-rolling regimes and correct existing such regimes for the controlled rolling of high-strength microalloyed steels.
