The necessity of dynamic precipitation for the occurrence of no-recrystallization temperature in Nb-microalloyed steel

▶ No-recystallization temperature is process-route dependent and an assessment based on composition is insufficient to predict this temperature. ▶ Dynamic precipitation is needed for the occurrence of a clear-cut Tnr. These precipitates best form at temperature range below 950 °C in the hot rolling process. ▶ Although Mean Flow Stress vs. 1000/T Method is a conventional method to predict the Tnr, it might not be sufficient to exactly determine this temperature.
