从实用的角度来看，轴承钢加载到非常高的循环疲劳状态，在服务中，远离Wöhler状态。本文讨论了加速疲劳试验、热耗散、鱼眼形成、夹杂物效应、短裂纹扩展和微观组织稳定性等方法，以期开辟109次循环范围内的研究途径。
For a practical point of view, the bearing steels are loaded up to the very high cycle fatigue regime, in service, far away from the Wöhler regime. In the present paper, several approaches are discussed in order to open some ways of investigation, in the range of 109 cycles: accelerated fatigue testing, thermal dissipation, fish-eye formation, inclusion effect, short crack propagation and stability of the microstructure.
