【Abstract】 The mechanical and dynamical recrystallization behavior of 60Si2MnA spring steel under hot deformation was investigated by hot simulation compression test. The activation energy of dynamical recrystallization and the relations of peak stress, peak strain, and grain size of dynamically recrystallized austenite with Zener Hollomon parameter Z were obtained. The results showed that the dynamical recrystallization can fine grain.更多还原
