L'objectif de ce travail est de prédire les risques de fissuration par H2S d'aciers au carbone à très haute limite d'élasticité utilisés en environnement pétrolier. Nous nous intéressons aux conditions de sévérité modérées, caractérisées par des teneurs faibles mais non nulles en H2S dans le milieu corrosif. Dans ces environnements, le chargement en hydrogène dans les aciers est lent, et les temps d'incubation avant apparition de fissures internes de type HIC peuvent donc être longs. En complément des essais standards de tenue à la fissuration des aciers, il est donc important de pouvoir disposer de méthodes rapides et fiables d'évaluation des risques de fissuration. La principale technique expérimentale mise en oeuvre est la perméation éle...
