Surface relief effect accompanying bainitic transformation in an Fe–C–Si–Mn alloy has been investigated by scanning tunneling microscopy (STM). It was discovered that a lower bainite subunit in an Fe–C–Si–Mn alloy is composed of sub-subunits, whose surface reliefs are tent-shaped, i.e. of a non-invariant plane strain (IPS) type, which is inconsistent with shear mechanism. The sub-subunit is idiomorphic, the height of its relief is 60–140 nm, and its maximum shape deformation is <I>ca.</I> 0.23. Multi-layer structure of bainite and effect of composition in steels on the ultrafine structure of lower bainite can be interpreted by the sympathetic nucleation-ledgewise growth mechanism.
