Abstract

The Inconel 617 alloy is used in the construction of boiler pressure elements with ultra-supercritical performance parameters. The paper presents the results of microstructure testing after 10,000 h ageing at 750 °C. Microstructure research was performed using scanning electron microscopy. The influence of ageing time on the changes in microstructure and the precipitation process in the native material, heat-affected zone and weld, which were referred to the changes in basic mechanical properties was described. The presented research results are an element of the material characteristics of the new generation alloys, which are used in design of pressure devices of steam boilers and diagnostic work during operation.
