“…In addition, no interaction between the c 0 free band and the oxide layer was observed in this study: localization bands were not preferential channels of oxide penetration in the base metal. This conclusion is in opposition to studies [16,20,22,23], reporting that the deformation bands present in 304L stainless steel exposed to PWR water may enhance the oxidation rate. For example, Lozano-Perez et al [23] indicate that prior cold work may facilitate oxidation in deformation bands by providing a density of dislocations acting as fast diffusion paths for oxygen and iron.…”

International audienceThe sensitivity of precipitation-strengthened A286 austenitic stainless steel to stress corrosion cracking was studied by means of slow-strain-rate tests. First, alloy cold working by low cycle fatigue (LCF) was investigated. Fatigue tests under plastic strain control were performed at different strain levels (Δεp/2 = 0.2%, 0.5%, 0.8% and 2%) to establish correlations between stress softening and the deformation microstructure resulting from the LCF tests. Deformed microstructures were identified through TEM investigations. The interaction between oxidation and localized deformation bands was also studied and it resulted that localized deformation bands are not preferential oxide growth channels. The pre-cycling of the alloy did not modify its oxidation behaviour. However, intergranular oxidation in the subsurface under the oxide layer formed after exposure to PWR primary water was shown

“…Many factors affecting corrosion rate and cracks growth were studied by several authors [74][75][76][77][78][79][80][81][82][83]. Nevertheless, the contribution of the oxide layers themselves remains crucial and is still suffering from a lack of understanding.…”

Abstract:Even if temperature, pressure and chemistry of the cooling water are not very high and aggressive, materials used in PWRs (Pressurized Water Reactors) are exposed to different degradation mechanisms. One of the main goals of the research programs in this field is to develop physical model of the mechanisms down to the atomic scale. Such approach needs a clear description and understanding of the degradation mechanisms at the same small scale. This paper illustrates the benefits of different microscopies and of their last improvements up to the promising possibilities of monochromated and aberrations corrected TEM/STEM. A specific focus is placed on four different degradation mechanisms observed in austenitic stainless steel: irradiation ageing, corrosion fatigue, stress corrosion cracking and corrosion.
