Abstract

In this work, the effect of NbC precipitates on corrosion fatigue behavior of E690 steel was investigated in simulated marine environment. It revealed NbC precipitates (especially dispersive and fine ones) can greatly improve the corrosion fatigue performance of E690 steel. They have beneficial effects on corrosion fatigue behavior through the four aspects: improving corrosion resistance, refining grain size, pinning dislocations ahead of crack tip and serving as irreversible hydrogen traps. This could provide an in-depth understanding and new strategy for designing corrosion fatigue resistant materials.
