Possibilities of Digital Optical Microscopy for Objective Certification of the Quality of Metalware

Аннотация

Simultaneous observation and measurement of microstructures in one and the same field of view (on one lap) by different methods is used to assess the information content provided by optical microscopy for certifying steel structures (sheets, profiles, forgings). The images of structures obtained under an optical microscope (in 256 tones of the gray color) are compared to the 3D images obtained under scanning and atomic force microscopes and to the orientations of the structural components (EBSD technique) in order to determine the nature of formation of images of unlike structures obtained by optical microscopy and to estimate the possibilities of digitization of the measuring procedures for controlling the quality of metalware in large-scale productions.
