                       Abstract:  The  wear-resistant  steel  was  subjected  to  single  pass  thermal  compression  deformation  at  high
                                                                        −1
                  temperatures (800‒1 200 ℃) and medium strain rates (0.1, 1, 5, 10 s ) with Gleeble-3800 thermal simulator. The
                  thermal compression deformation behavior of the steel was studied. According to the true stress-true strain data, the
                  traditional Arrhenius equation was improved by introducing the influence of the true strain, and then the constitutive
                  model was established. The calculated results were compared with test results. The hot processing map was drawn to
                  determine the reasonable processing range. The results show that the flow stress of the test steel decreased with the
                  increase of deformation temperature or the decrease of strain rate. With the increase of deformation, the true stress first
                  increased to the peak stress and then became stable, except at high temperature (not less than 1 100 ℃) and low strain
                         −1
                  rate (0.1 s ), the true stress first decreased slightly after reaching the peak stress and then became stable. The true stress
                  obtained by the established constitutive model was in good agreement with the test results, with the average relative error
                  of 3.79% and the linear correlation coefficient of 0.997 5, indicating that the constitutive model could accurately predict
                                                                                                        −1
                  the rheological behavior of the test steel at the deformation temperature of 800‒1 200 ℃ and the strain rate of 0.1‒10 s .
                  The reasonable processing range of the test steel under single pass thermal compression deformation was true strain of no
                                                     −1
                  more than 0.5, strain rate of no more than 10 s , and deformation temperature of 900‒1 100 ℃.
