Visualization of the Bainite Fine Structure Using EBSD and Euler Angles


The electron backscatter diffraction method (EBSD) is widely used to study

crystallographic orientational relationships of the steel microstructure constituents

including bainite. Nevertheless the fine structure of bainite (subunits, 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 values of Euler angles

obtained by EBSD method. A three-dimensional picture of the bainite fine structure of

the HY-TUF steel obtained by the proposed technique is in
