Abstract Scope The effect of pre-straining on the corrosion resistance of dual-phase austenitic-ferritic S32304 lean duplex stainless steel has been studied in acidic chloride medium. After interrupted tensile testing, potentiodynamic experiments allowed to study cathodic (Hydrogen Evolution Reaction) behavior for pre-strain levels ranging up to 20%. Rigorous surface preparation allowed to distinguish the role of the emergence of slip steps and dislocations lines, from those of other mechanical and metallurgical parameters. A non-monotonous effect of the emergence of slip steps and dislocation lines on cathodic currents has been observed. Kinetics increased up to four times for a 3% strain level, and then progressively decreased. This behavior is studied in terms of modification of the surface Electron Work Function by correlation with Atomic Force Microscopy analysis. The anodic behavior (dissolution and passivity) has been studied by local electrochemical technique using microcapillaries. Results are discussed based on tensile testing in-situ residual stress measurements.
