%X Surface relief effect and their corresponding microstructure accompanying bainitic transformation in the steel Fe--0.33C--3.0Mn--2.15Si--1.25Ni (mass fraction, %) were studied by atomic force microscope (AFM). The results show that surface relief of bainite is produced by bainitic ferrite solely without the involvement of austenite. Furthermore, surface relief of a single structural unit is tent--shaped rather than invariant--plane--strain--typed and the tilt angles of the two sides are 9--10 and 8--9, respectively close to the magnitude expected from the diffusional ledgewise growth mechanism.
