The dynamic recrystallization (DRX) and flow stress of Nb-bearing steels were investigated by means of isothermal single compression testing at temperatures of 850-105° and at constant strain rate from 0.1 to 20s-1 using a Gleeble 3800 thermo-mechanical simulator in order to model the DRX processes...
