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.

应力集中条件下单晶耐热镍合金的高周疲劳

我们研究了由实验性低碳单晶耐火镍合金制成的测试缺口试样的高周疲劳，这取决于晶体取向和测试温度。单晶高周疲劳极限的各向异性是微不足道的。试验温度从20℃升高到900℃，导致高周疲劳曲线形状发生变化。用断口法研究了疲劳断裂的特征。
