When the true strain is 0.8 and deformation temperature is in the range of 1223 ~ 1323 K full dynamic recrystallization occurs in the test steel at strain rate of 0.2 ~ 10 s ~ -1.The hot deformation activation energy Q of test steel is 289.9 kJ / mol.

试验用钢在 真应变为0.8，温度为1223~1323K，应变速率为 0.2~10s-1的条件下，发生完全动态再结晶。
