摘要
Results are given for experimental studies on fatigue resistance of refractory nickel alloys (deformable EP109 and casting ZhS6U) obtained for smooth specimens and specimens with a round notch at an elevated temperature and with different stress ratios. The effect of stress concentration on fatigue resistance is shown to depend on the alloy type and amplitude coefficient, the experimental time exerting a slight influence.
