RT info:eu-repo/semantics/article T1 Comparative study between large-scale and small-scale electrochemical potentiokinetic reactivation performed on AISI 316L austenitic stainless steel A1 Martín Llorente, Óscar A1 Tiedra Frontaura, María del Pilar A1 García Cabezón, Ana Cristina A1 Martín Pedrosa, Fernando A1 López Aparicio, Manuel Federico K1 Stainless steel K1 Polarization K1 Effects of strain K1 Intergranular corrosion K1 Welding AB This work optimizes the application of electrochemical potentiokinetic reactivation (EPR) to assess the degree of sensitization (DOS) of AISI 316L and compares the large-scale and small-scale EPR with the aim of improving the study of the different zones of AISI 316L welded joints by using an electrochemical minicell. The optimized EPR allows to discriminate better than the standardized EPR among different DOS. Small-scale EPR shows greater sensitivity to assess the DOS than large-scale EPR: (i) at lower deformation levels; (ii) for shorter sensitization times; (iii) when localized microstructural regeneration is caused by the combined effect of deformation and subsequent sensitization.
