Abstract

Les aciers inoxydables austénitiques non sensibilisés peuvent subir dans l’acide nitrique un type de corrosion intergranulaire (CIG) particulier. Un modèle d’estimation de la durée de vie de ces matériaux dans ces milieux est proposé. Il reproduit de manière fiable les cinétiques de corrosion obtenues expérimentalement.
