Abstract


Non-recrystallization temperature (Tnr) and phase transformation temperature during cooling (Ar3) of a medium carbon, vanadium-microalloyed steel have been determined by means of hot rolling simulation under different conditions of strain applied and interpass time. The stress accumulated in the austenite at temperatures between Tnr and Ar3 (Δσ) has been measured on MFS curve and the influence of the deformation conditions on Tnr and Δσ values has been studied. Tnr and Ar3 are the temperature limits where last passes of industrial rolling should be accomplished in order to obtain a strengthened austenite leading to a finer final microstructure.
