It was found that the addition of carbon prolongs the transformation incubation period dramatically, which retards the ransformation kinetics. However, the ransformationincubation period is somewhat prolonged, and the kinetics becomes much more sluggish as the manganese content increased. The more pronounced refinement is achieved as the carbon or manganese content increased because of the higher nucleation rate, especially in the steels with high carbon content. The process of DEFT in the tested steels can be divided into three stages according to the characteristics of the DEFT kinetics, the first stage obeys Cahn site saturation mechanism, but the other two stages not.
