0. 21 ~0. 40N) is melted by a 10 kg vacuum induction furnace with adding chromium nitride to N-alloying in nitrogen atmosphere. The compression 60% experiment of test steel in vacuum with strain rate 10

at 1 150 ~ 1 000 ℃ has been carried out by using Gleebl-1500D thermo-mechanical simulation machine. Test results show that at high temperature with lower strain rate the dynamic recrystallization of steel is main softening mechanism and with higher strain rate the dynamic recovery of steel is the main softening mechanism as compared with 0. 21
% N and 0.29% N test steels the 0. 40% N test steel has higher peak stress
and based on the calculation of Zener-Hollomon parameter
the recrystallization activation energy of 0. 40% N test steel is highest
uneasily to happen dynamic crystallization at elevated temperature.
