The present study focuses on the completely recrystallized grain growth of NiCrMoV steel.All the samples were austenitised at 1250℃ for 5min,and then were compressed with strain rate of 0.01s~(-1) and finial strain of 0.8.Once the compression completed,the specimens were held for different time before water quenching.Based on the experimental results,the completely recrystallized grain growth model was established and the effects of temperature and holding time on austenite grain size were investigated.Comparison between the experimental and predicted results was carried out.A good agreement between the experimental and predicted results verifies the developed model.
