HOT-DEFORMATION BEHAVIOR AND PROCESSING MAP OF 22MnB5 HIGH-STRENGTH STEEL
In order to explore the hot formability of 22MnB5, a hot-tensile test of 22MnB5 high-strength steel plate was carried out using a Gleeble-1500 hot-tensile-testing machine. The stress-strain curves at 850 °C to 950 °C and 0.01 s–1 to 10 s–1 were obtained. The results show that 22MnB5 has an obvious positive-strain-rate sensitivity, and its peak stress decreases with the increase of temperature. The mechanical constitutive equation of 22MnB5 was established by using the improved Johnson-Cook model, and the fitting value was compared with the experimental value. Based on the dynamic material model, the hot-processing map of 22MnB5 was established and analyzed. The hot-processing process was determined as follows: deformation temperature 880 °C to 930 °C, strain rate 0.01 s–1 to 1 s–1.
