Static recrystallization modelling of hot deformed steels containing several alloying elements

Abstract

Using torsion tests a model has been constructed to predict the recrystallized fraction of deformed austenite in low alloy and microalloyed steels. The model quantifies the influence of the most common elements (C, Si, Mn, Mo) in low alloy steels and the typical elements (Ti, V, Nb) in microalloyed steels in the recrystallized fraction, when they are in solution. Static recrystallization kinetics follow Avrami's law and expressions for the parameter t0.5 and for the exponent n are not given. The values predicted by the model are compared with the experimental values, good concordance being obtained between both.
