The electron backscatter diffraction method (EBSD) is widely used to study crystallographic orientational relationships in the microstructure constituents of steels, including bainite. Nevertheless, the fine structure of bainite (subunits and plates) is not investigated by this method. In this paper we propose a technique for visualizing of the structure of a bainitic steel near-surface layer using the Euler angles obtained by EBSD method. A three-dimensional picture of the bainite substructure of the HY-TUF steel obtained by the proposed technique is in satisfactory agreement with the data obtained earlier by the atomic force microscopy.
