Abstract


A method is described which allows to study the interaction recrystallization-induced precipitation by the deformation of vanadium microalloyed steel and 0.35 % C. By means of torsion tests and applying the Back Extrapolation method, the recristallized fraction at different temperatures has been determined. When the precipitation begins, the recristallized fraction does not follow the Avrami's equation. This allows to know the instant when precipitation starts (Ps) and the instant when precipitation finishes (Pf). Therefore, Recrystallization-Precipitation-Time-Temperature (RPTT) diagrams can be obtained, which graphically show the interaction Recrystallization-Precipitation and simultaneously allows the determination of the static recrystallization critical temperature (SRCT). This temperature represents the limit between the two phases, before and after precipitation.
