A method for rapid determination of former austenite grains in bainitic-martensitic steels employing standard software for processing the results of mapping of crystallographic orientations obtained by electron back-scatter diffraction analysis in a scanning electron microscope is proposed. The method is verified for orientations of retained austenite in steel 09KhN2MD.
