摘要	Corrosion fatigue (CF) tests of 316LN weld metal were investigated in high-temperature water at different strain rates (0.0004-0.4%/s) under strain amplitude of 0.6%. Relationship between CF life and strain rate was proposed and environmental fatigue correction factor F-en was also calculated. It was found that the gamma/delta phase boundary was more susceptible to cracking at low strain rates and 6-ferrite worked as a barrier to retard the crack growth at high strain rates. Mechanisms of CF damage involving the effects of strain rate, hydrogen, 6-ferrite and residual strain on crack growth are also discussed.
