Abstract

The change in the austenitic microstructure of plain carbon steels in multipass continuous hot working processes has been investigated by using a high speed hot deformation simulator. The critical strain for the occurrence of dynamic recrystallization, the kinetics of dynamic and static recrystallization, and the grain size developed by recrystallization and grain growth have been determined experimentally and formulated in terms of hot deformation variables and initial grain size. To evaluate the effect of the residual strain of prior deformation on the recrystallization behaviour quantitatively, a relationship describing the change in dislocation density during and after deformation has been derived from analysis of the stress strain curve. A calculation model consisting of these relationships is used for the prediction of microstructural change in commercial hot rolling practices. Good agreement between the prediction and measured results was obtained.
