Abstract
Fatigue crack growth properties for stainless steels, SUS304 and SUS403, and low alloy steel, Cr-Mo-V, at temperatures between 25 and 550°C and frequencies between 0.0005 and 50Hz. Fatigue crack growth rates were accelerated with increasing the temperature and with decreasing the frequency for all three steels. SUS403 and Cr-Mo-V steels exhibited the transgranular fracture mode, while SUS304 steel exhibited both the intergranular fracture and transgranular mode at higher temperatures and lower frequencies. The effects of Young's modulus, yield strength, oxidation and creep damage on the behavior of elevated-temperature fatigue crack growth were discussed on the basis of Laird's model [12].
