摘要：Corrosion fatigue and electrochemical tests under proportional loading and non-proportional loading were conducted on 304 stainless steel in 0.63 mol L-1 NaCl solution at room temperature. Two biaxial loading paths were applied to study the effect of proportional loading and non-proportional loading on corrosion fatigue behaviour. Surface and fractographic observations of multiaxial corrosion fatigue specimens were carried out by scanning electron microscopy. It was shown that proportional loading had a more significant effect on the occurrence of local corrosion compared with non-proportional loading because the continuous rotation of the principal stress plane under non-proportional loading inhibits the pit formation.
