To study the mechanisms of high-temperature fatigue in the heat-resistant nickel-based superalloy Udimet 720, the aging process has been physically simulated by high-temperature exposure at temperatures of 850, 1000 and 1200°C. The patterns of changes in the parameters of the microstructure and mechanical properties of the material during artificial aging of this alloy have been established.
Berdnik et al. (Sat,) studied this question.
