Abstract Through the analysis of parts failed in service by electronfractography andfracture mechanics, and by corrosion fatigue (CF) and stress corrosion cracking(SCC) experiments, it was shown that under the condition of CF,the crackingmorphology of steel is not merely governed by a single mechanism. It dependsupon the critical stress intensity factor of the steel K_(IC), CF maximum stress in-tensity factor K_(Imax), threshold SCC intensity factor range △K, frequency f, stressratio R, etc. In case of (dK/da)>0, three basic fracture morphologies wereobserved: (a) when K_(Imax)
