Abstract Scope The crystallography and morphology of bainite formed at the austenite (γ) grain boundaries in 0.6wt% C steel were studied by 3D observation using serial sectioning technique and EBSD. The steel samples were austenitized at 1273 K for 10 min, and subsequently cooled down to and isothermally held at 623 K for bainite transformation; when the bainite transformation proceeded to a certain degree, they were quenched to stop bainite transformation. In the early stage of transformation, the bainite forms almost parallel to the γ grain boundary plane and sometimes contacts with the grain boundary edge, suggesting that they act as nucleation site of bainite. The effect of these boundaries on the bainite formation was investigated not only the planer grain boundaries but also the grain boundary with curvature. The results suggested that the orientation of the γ grain boundary is more important for the formation of the bainite.
