We study high-cycle fatigue of tested notched specimens made of experimental low-carbon singlecrystal refractory nickel alloy depending on the crystallographic orientation and testing temperature. The anisotropy of the high-cycle fatigue limits of single crystals is insignificant. The increase in the testing temperature from 20 to 900°C leads to changes in the shape of the curve of high-cycle fatigue. By the fractographic method, we study the character of fatigue fracture.
