Mathematical Modeling of the Recrystallization Kinetics of Nb Microalloyed Steels

摘要

The recrystallization behavior of Nb microalloyed steels was studied using hot torsion testing with the aim of modeling the recrystallization processes taking place during hot rolling. Continuous and interrupted tor- sion tests were performed in the temperature range 850 to 1050deg C at strain rates of 0.05 to 5/s on selected low carbon steels containing Cr, Mo, Nb, Ni and Ti.
