摘要

Double-hit hot compression tests were carried on medium-carbon low-alloy steels using Gleeble 3800(R)thermomechanical simulator. The experiments were performed at strain rates of 0.25 and 0.5 s(-1)and temperatures of 1150 and 1200 degrees C with interpass times of 5, 15, and 25 s. The onset of critical stresses for dynamic transformation (DT) for both first and second hit were detected using the double-differentiation method. It was found that the critical stress for DT increased with a decrease in temperature and an increase in strain rate. The presence of dynamically transformed ferrite was observed and quantified using electron-backscatter diffraction, kernal average misorientation, and grain boundary maps. Then, a thermodynamic analysis was carried out using JmatPro software. A method of determining the change in Gibbs energy during DT phenomenon is proposed for double hit deformation. Graphic
