The process of the consuming incubation period for bainitic transformation during continuous cooling, of steels was examined in the relation with consumption of incubation period for ferritic or pearlitic transformation by steels of JIS SUJ2, SCM5, and SNCM8. The main results are as follows: (1) There is a critical temperature (AB) at which the consumption of incubation period for bainitic transformation starts during continuous cooling.
(2) The consumption of incubation period for bainitic transformation is progressed independently of any consumption of incubation period for ferritic of pearlitic transformation.
(3) The bainitic transformation behaviour after a change of cooling rate during continuous cooling shows a different manner from that indicated by a usual CCT-diagram of the steel because of the different way in consumption of the incubation period. The estimation method of the transformation behaviour in such a case was explained by using usual CCT-diagram.
