Abstract
Turbine, compressor, and rotor disks are critical elements of an aircraft engine. The repeated heating and cooling to which the disks are subjected during operation cause an accumulation of plastic deformation and development of fatigue rupture. Therefore, it is important to know in what way the nickel alloys lose strength and fail in the process of long-term operation at high temperatures. The aim of the present work is to investigate the effect of various structural parameters on the processes of deformation and rupture of high-temperature nickel alloys used for disks of gas-turbine engines under conditions close to the operating ones.
