It was discovered that the surface relief due to Widmanstatten ferrite formation appears to be of tent-shaped type, or complex type.The evolution of surface relief of Widmanstatten ferrite can be more interpreted by ledgewisegrowth mechanism rather than by displacive mechanism. The height of relief is 70-450 nm, and the maximum shape deformation is ca. 0.36.
