Effect of Mo concentration on dynamic recrystallization behavior of low carbon microalloyed steels

Journal Article


Abstract


  • Using a Gleeble 3500 thermo-mechanical simulator, the dynamic recrystallization (DRX) behavior and mechanical properties of four low C, Nb-Ti-containing micro-alloyed steels with a Mo content ranging from 0 to 0.27 wt% were investigated. The effects of Mo content, deformation temperature and strain rate on the DRX parameters were quantified. The flow curves showed the typical signs of DRX over a wide range of deformation conditions. However, at higher strain rates (5 s-1) and/or lower deformation temperatures (below 1000°C), dynamic recovery was observed. It was shown that Mo has an effect on retarding DRX in micro-alloyed steels, most likely due to the solute drag. Dynamic recrystallization (DRX) and mechanical properties of microalloyed Nb-Ti-steels with different Mo contents are investigated, and the effects of Mo, deformation temperature and strain rate quantified. The typical signs of DRX are observed over a wide range of deformation conditions, but at higher strain rates and/or lower deformation temperatures, dynamic recovery occurred. It is shown that Mo has a retarding effect on DRX.
