Abstract
At 470 degree C strain holding had generally no influence on fatigue strength but life reduction was observed in compressive strain holding tests at low strain. Life reduction was also observed in zero stress holding tests. Based on the observation of the oxide film, a mechanism is proposed The life reduction is closely related to the acceleration of fatigue crack initiation due to oxide cracking. The fatigue life of fast breeder reactor components is predicted on the basis of the proposed mechanism. The life under compressive strain holding turned out to be 10% of that of continuous cycling.
