    Abstract

    An investigation of the below KIscc corrosion fatigue crack propagation behavior of 5Ni-Cr-Mo-V steel in a 3½ percent NaCl environmental solution is conducted with particular emphasis on the influence of frequency and temperature. The behavior is described using a generalized equation which incorporates the influence of temperature, frequency, and stress intensity range. The generalized equation dadNC=dadNF{H(ΔK,f,T)} relates the corrosion fatigue crack growth rate, dadNC, to the baseline cycle-dependent fatigue crack growth rate, dadNF. The function H is an environmental enhancement multiple. The severity of the temperature influence on environmentally enhanced fatigue crack growth rates of steels in aqueous environments appears to be related to the inherent resistance of the material to environmental cracking.
