摘要：
Multicycle fatigue of an experimental low-alloy single-crystal nickel-base superalloy is studied in relation to crystal orientation and test temperature. It is established that with an increase in test temperature from 20 to 900°C a change is observed in the shape of the multicycle fatigue curve. Scanning electron microscopy is used to determine the nature of fatigue failure. The work was conducted within the scope of a priority area for development of RF science, technology, and engineering, i.e., transport and space systems.
