Abstract Various types of carbide precipitation have been observed in steel 10 and 20SiMnMo during isothermal transformation. It seems that two interphase precipitation processes may occur. One of them takes place at the temperatures between pearlite and Bainite transformation, it may be associated with massive transformation and occurs mainly through a random transfer of atoms across γ/α interphase. Another involves bainite transformation, Ledge-propagation mechanism is the dominant feature of interphase precipitation. Both of them have been observed by means of TEM determination.
