With the development of scientific and technical progress the value of information about the physical characteristics of structural materials is continuously increasing. This is due to the fact that the safety factors in engineering are significantly reduced, providing improved material consumption indicators at constant complication of working conditions of machinery and equipment. Grow and requirements to the accuracy of the measurement of physical and mechanical properties of materials, their co mpleteness, reproducibility and efficiency. The complexity of the test equipment, its highly specialized nature, a variety of samples types used for the measurements of the properties of materials increases the costs for the information support of modern production. The use of photometric systems for the determination of the structural characteristics of the materials to a large extent can satisfy the entire range of modern requirements for methods of measuring their properties. The group of authors developed a photometric analyzer of structural images (PHASI) that allows the joint analysis of video fragments of the surface of the objects, and the spectra of the brightness of reflection them in the optical range in the physical or chemical effects on them, evaluate the quantitative measure of the strength of materials these effects, i.e. their actual physical characteristics. Development of photometric image analysis methods (PHASI) opens possibilities for measuring thermo physical properties and structural changes occurring in the process. The present work is devoted to the analysis of thermal characteristics of steel and structural changes in it, which accompany the measurement process. The experimental part was carried out on a steel 02H21N11G2B.
