“…At the initial state the pit shape is globular, whereas at ϵ = 9% and ϵ = 18% the pits are more elongated as a consequence of a selective corrosion of the formed deformation bands and α′‐martensite (Figure d–f). The evaluation of the pit density revealed 44 pits cm −2 for the initial state, 71 pits cm −2 at ϵ = 9%, and 102 pits cm −2 at ϵ = 18%. Consequently, the increase in pit density is a coupled result due to the enhancement in corrosion sensitivity after a plastic deformation.…”

“…Due to this phase transformation the mechanical properties, named ultimate compressive stress, tensile strength, and uniform elongation, are increased significantly . With focus on the corrosion behavior, the sensitivity against an aggressive solution strongly depends on the formed passive oxide, which is directly influenced by mechanical stresses …”

The influence of plastic deformation on the electrochemical corrosion behavior of a meta‐stable high‐alloy CrMnNi steel is investigated in a 5 wt% sodium chloride solution by cyclic voltammetry. Interrupted tensile tests are performed to attain two defined states of plastic deformation. The formation of straight slip bands and deformation‐induced α′‐martensite is observed in the austenite of the tensile samples which are deformed up to fracture. The deformation‐induced α′‐martensite fraction is evaluated by an in situ magnetic measurement method simultaneously to the tensile test. Microscopic observations after the potentiodynamic polarization revealed pitting corrosion at all surfaces. Furthermore, a strong dependency between applied anodic potential and degree of plastic deformation at forward polarization is found, whereas the reverse scan exhibits a significant influence of the pitting corrosion attack. Consequently, the forward polarization behavior is dictated by the previously applied mechanical stress, whereas the influence disappears when pits have been formed.

“…This is an efficient method for detecting the early stages of coating degradation [44][45] and identifying precursor sites in stainless steels [46]. It consists in applying a potential EA for a certain duration (15 or 40 seconds) and then a potential of -360 mV vs. Ag/AgCl in the cathodic domain (passive behaviour) for 2 seconds.…”

“…Regarding the performance of low-C martensitic stainless steels, Vignal et.al. [3] stated very recently that Bthere are still open questions concerning the relationships between the specimen microstructure, the passive properties of the alloy and the corrosion mechanisms.^This is the knowledge gap we intend to bridge here.…”

“…Thus, when corrosive conditions are not particularly severe, the use of these stainless steels becomes quite attractive due to their lower cost, which makes them the natural choice for the replacement of either carbon steels that have a lower corrosion resistance or duplex stainless steel grades having higher prices [1][2][3][4].…”

Mott-Schottky analysis and electrochemical and X-ray photoelectron spectroscopy (XPS) measurements were performed on passive films formed on low-C 13CrNiMo stainless steel with different applied heat treatments. Heat treatments render particular microstructural features of the alloy with a significant impact on the ability of the passive films to afford adequate protection against localized corrosion. A lower level of retained austenite in the substrate renders thinner passive films. Phosphates coexist with oxidized Fe(III) compounds as the prevailing species in the anodic layers. Mo was only detected in the oxide film formed on the sample with a higher retained austenite content.Passive layers behave as n-type semiconductors with two types of donors, namely, shallow-level and deep-level states. The observed flat band potential V FB ≅ -0.425 ± 0.005 V vs. standard calomel electrode (SCE) is independent of the thermal treatment of the alloy but under potential bias conditions at the corrosion potential the occurrence of the cathodic reaction on the oxide surface is hindered on the sample with higher retained austenite in its microstructure as compared to the sample with lower retained austenite content.
