Characterization and Modeling of Softening Kinetics during Hot Deformation in Modern Steels

Article Preview

Abstract:

A model describing the kinetics of static recrystallization and the kinetics of Nb and Ti precipitation has been reconsidered for modern steels. The effects of alloying and microalloying elements have been introduced into the model. The comparison of the modeling with the experimental softening shows good agreement.
