Abstract

Annotation. Purpose. The analysis of the phase state of steel 03Х17Н3Г9МБДЮч and influence of operation temperature on the mechanical properties, heat resistance and corrosion resistance. Methodology. Samples of high-temperature corrosion resistant steel 03Х17Н3Г9МБДЮч (patent UA №100650). Findings. The study of the distribution of alloying elements was carried out on scanning electron microscope РЕМ-106I, equipped with a system of x-ray energy dispersive microanalysis at an accelerated voltage 20kV secondary electrons. X-ray microanalysis (RSMA) shows the distribution austentatious and ferritotious elements in stainless steel 03Х17Н3Г9МБДЮч. Practical value. Established in 03ХН3Г9МБДЮч steel at high temperatures of operation is dominated by austenite structure, this helps to preserve its strength and hence the durability of the reactors.
