Notes:
Rotating bending fatigue tests were carried out to investigate the effects oftemperature on the fatigue strength and the fracture mechanism of an 18 % Ni maragingsteel at room and elevated temperatures of 473K and 673K. Fatigue strength was higherat elevated temperatures than at room temperature, though static strength was decreasedby softening at elevated temperature. There was no effect of temperature on crackmorphology and fracture mechanism. On the other hand, during fatigue process atelevated temperature, the specimen was age-hardened and the specimen surface wasoxide. That is, the increase in fatigue strength at elevated temperature was mainlycaused by the increase in hardness due to age-hardening and suppression of a crackinitiation due to surface oxidation
