Study of Ageing Processes of a Nickel Superalloy under Conditions of High-Temperature Loadings

Abstract:

The results of studies of microstructure and of mechanical properties of the superalloy Udimet 720 in initial and aged states at various temperatures (850 °С, 1000 °С и 1200 °С) are presented in the paper. Mathematical processing methods were used during the analysis of morphological and geometric characteristics of strengthening phases in the alloy. Dependencies of mechanical properties indices on parameters of strengthening phases of the microstructure have been revealed. It has been found that the downtrend of strength and plastic characteristics of the alloy that was aged at high temperatures is due to changes in morphology and content of intermetallic phase.
