The metadynamic and static recrystallization behavior in hypereutectoid steel containing 1% carbon was determined by hot compression testing. Compression tests were performed using double hit schedules at temperatures between 900 to 1050°C, strain rates of 0.01 to 1 s−1 and recrystallization times of 0.1 to 500 s. The characteristics of static and metadynamic recrystallization are distinctly different. Results show that the metadynamic kinetics was twice as fast as the static kinetics. These data were used to generate equations to predict the kinetics of static and metadynamic recrystallization, as well as the evolution of grain size, after recrystallization.
