The effects of primary ferrite on bainitic transformation, microstructure, and properties of low carbon bainitic steel Fe – 0.22C – 2.01Si – 2.20Mn – 0.22Mo are investigated by metallographic and dilatometric methods. It is found that the effect of primary ferrite on subsequent bainite formation appears as a change in the ratio of two competing processes: advance of the austenite–ferrite interface and its retardation due to retained austenite stability.
