The recrystallization behavior of a Nb-bearing steel was investigated during multipass deformation under continuous cooling conditions. By a series of six-pass compression tests conducted on a thermomechanical simulator, the effect of deformation parameters, including strain, strain rate and interpass time, on the no-recrystallization temperature (T) was determined. The results show that T decreases with increasing strain and also decreases slightly with increasing strain rate. The strain has more appreciable influence on the T compared with strain rate. When the interpass time is less than 10 s, the T decreases with increasing interpass time. The mathematical model of T was established considering the effect of pass strain, strain rate and interpass time. The calculated results agreed well with the actual experimental value. 展开更多
