MAREK SROKA, MARCIN NABIALEK, MICHAL SZOTA, ADAM ZIELINSKI THE INFLUENCE OF THE TEMPERATURE AND AGEING TIME ON THE NICR23CO12MO ALLOY MICROSTRUCTURE The NiCr23Co12Mo alloy (Inconel 617) is a material used for example in the production of superheater boilers with ultra-cool supercritical parameters of work. The paper presents the results of microstructure changes after the long-term impact of temperature and strain. Analysis of the microstructure was carried out using scanning electron microscopy. Qualitative and quantitative identification of precipitations were conducted using X-ray analysis of the phase composition. Was studied the influence of ageing on tested alloy precipitations. The results of the study are the database alloy material of the new generation, which is used in the activities of the diagnostic elements of pressure parts of boilers.
