摘要：
The dynamic recrystallization behavior in hypereutectoid steels with different carbon content was determined by hot compression testing. Compression tests were performed using single hit schedules between 800 to 1050 degrees C, strain rates of 0.01 to 1 s(-1). It was found that the critical stress for the start of dynamic recrystallization is almost same as the steady state stress. The results also revealed that the carbon content has no effect on the activation energy of deformation.
