Abstract: The corrosion fatigue behavior of stainless steel 3RE60 in 3.5%NaCl solution wasstudied at different cyclic stress levels. The results showed that both intergranularcorrosion cracking and transgranular corrosion cracking initiated at the bottom ofpits. The corrosion fatigue behavior of 3RE60 may be related to complex electrochem-ical and mechanical coupling effects between the three phases (austenite, ferrite andmartensite), where martensite and ferrite were anodic in the corrosion cell and couldbe prone to crack under certain conditions.

Key words: corrosion fatigue, stainless steel 3RE60, phase electrochemical, dislocation
