- High-temperature random vibration fatigue; S-N curve; GH188 superalloy
- A random vibration fatigue test system developed by the company was used to conduct a random vibration fatigue test at a temperature of 25? /450? for a typical plate element of GH188 alloy, and the random vibration fatigue median life of S-N curve of GH188 superalloy at a temperature of 25?/450? was obtained. The experimental results show that under the condition of 450? the S-N value of the random vibration median life of the GH188 deformed superalloy is lower than that of the room temperature, indicating that the fatigue life of the GH188 deformed alloy is shortened with the increase of temperature.
