Abstract

A method developed in the CENIM is described which allows to study the interaction recrystallization-induced precipitation by the deformation of vanadium microalloyed steel. By means of torsión test and applying the back extrapolation method, has been determined the recristallized fraction to diferent temperatures. When the precipitation begins, the recristallized fraction is separated of the Avrami's equation and this allows to know the instant the precipitation begins (P_s) and the instant the precipitation finishes (P_f). Thereby can be traced the Recrystallization- Precipitation-Time-Temperature (PTT) diagrams, which graphically show the interaction Recrystallization-Precipitation and simultaneously allows the determination of the static recrystallization critical temperature (SCRT). The mentioned temperature represents the limit between the two phases, before and after of the precipitation.
