Surface relief caused by the formation of lower bainite in an Fe-C-Si-Mn alloy has been investigated by STM. It was discovered that the subunit which is the lowest structural unit observed by TEM is actually made up of sub-subunits. The surface relief due to the formation of sub-subunit is tent-shaped, and of a non-IPS type, which indicates that the sub-subunit cannot be formed by shear. The height of relief is 60-140nm, and the maximum shape deformation is ca.
