Resumo

The substructure and microstructure of pearlite in hypoeutectoid low-carbon steel 09G2S is studied using high-contrast images in a scanning electron microscope and electron backscattered diffraction. Acorrelation is established between local deviations from “ideality” in the structure of pearlite and the substructure of pearlitic ferrite. Fragments of pearlitic ferrite, whose development is connected with propagation of long-range misorientations, are seen. It is shown on the basis of visualization that the single-crystal matrix of the pearlitic ferrite consists of individual fragments. These fragments are not generally flat.
