Résumé
Des essais de traction à grande vitesse de déformation menés à température ambiante et à 300°C sur du Zyrcaloy ayant subi différents traitements sont analysés et comparés à ceux obtenus sous sollicitations statiques. Il est observé que l'allure des courbes contrainte - déformation dépend du traitement subi par l'échantillon et que les valeurs les plus fortes du pic de contrainte et les réductions les plus marquées de striction sont obtenues lors des essais à grande vitesse de déformation.
Abstract
High strain rate tensile loading behaviours of Zircaloys subjected to various treatments were investigated at room temperature and at 300°C, and compared with those of static cases. It was observed that the dynamic stress-strain profiles were different depending upon the specimen treatment and that the higher peak stress and the lower sectional area reduction were always recognized in the high strain rate cases.
