description: The loss of the corrosion resistance of the alloy 600, a nickel base alloy, during the oxidation in pressurized water reactor (PWR) has been demonstrated by many studies. It induces the intergranular stress corrosion cracking (IGSCC). If the chemical composition and the structure of the growing oxide are well-known, the mechanical influence of the oxide on the alloy has not been fully studied, yet. This study aims at bringing new knowledge of the oxidation impact on the mechanical response of the alloy. A new methodology is introduced for determining the local nanodeformation of the alloy 600 induced either by an oxidation or by a tensile loading. This method is based on nanodots disposed at the alloy surface as local markers of position. The statistical analysis of these data allowed to determine rare events of high deformation The samples were characterized locally by SEM, TEM, XPS and spectroscopic ellipsometry to characterize the internal oxide which constrains the alloy. The coupling of the EBSD with the nanodots had enabled to determine a set of parameters, which was used as an alarm criterion for the IGSCC initiation.
