The occurrence of dynamic recrystallization in hypoeutectoid and hypereutectoid steels of 0.7 and 0.9% carbon was investigated under isothermal conditions. Compression tests were performed using single deformation schedules at temperatures between 900 and 1050 °C and strain rates of 0.01s-1, 0.1s-1 and 1s-1. It was observed that the activation energy for deformation decreased with increasing carbon content in the steels. The peak and steady state strain values determined from the flow curves generated by hot compression deformation were used to examine the possible evolution of grain size by recrystallization.
