In this investigation, the change in incubation period for isothermal bainitic transformation was observed with precipitation of primary carbide or ferrite from the austenite before the transformation in hypereutectoid steel JIS (SUJ 2) or hypo-eutectoid steel JIS (SNCM 8), respectively. The main results are as follows : (1) The incubation period for upper bainitic transformation is remarkably shortened with the precipitation of the primary carbide, while that for pearlitic transformation is slightly affected. (2) The incubation period for upper bainitic transformation is also remarkably shortened as the content of carbon in austenite is decreased. (3) The incubation period for upper bainitic transformation is prolonged with the precipitation of the primary ferrite. (4) The incubation period for lower bainitic transformation is shortened with the percipitation of the primary ferrite.
