Abstract The change of corrosion fatigue(CF) fractography with stress ratio (R) and frequency (f) were studied in distilled water and 3.5％ NaCl aqueous solution. It is shown that the variations of CF fractography with increase in R or decrease in f are similar, i. e., the tendency of stress corrosion cracking (SCC)fractography increased with increase in R or decrease in f on CF fractography. A mechanism schetch map of crack propagation which indicated the influence of R and f on CF cracking mechanism was presented.
