The influence of deformation and cooling rate as well as Nb content on the α-phase starting temperature was thor- oughly investigated. The results given by the model were in good agreement with the experimental results, which showed that the model could predict the α-phase starting temperature for high Nb pipeline steel during cooling process.展开更多
