Effect of Mo concentration on dynamic recrystallization behavior of low carbon microalloyed steels
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 percent 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 conditoins. However, at higher strain rates and/or lower deformation temperatures 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.
