Selective dissolution and its effect on fatigue crack initiation in 2205 duplex stainless steel (DSS) were investigated. In mixed H2SO4/HCl solutions, two distinct and separated anodic peaks appeared in the active-to-passive transition region of the po-tentiodynamic polarization curve. Selective dissolution at each of these characteristic potentials was demonstrated. Under sinusoidal cyclic loading condition, selective dissolution did not assist fatigue crack initiation, instead resulting in the elimination of stress concentration site in the selectively dissolving phase. Microstructural evolution of the corrosion fatigue crack initiation in 2205 DSS in the mixed H2SO4/HCl solution and under selective dissolution condition was presented.
