Résumé
Trois aciers à matrice ferritique avec des silicates et sulfures comme inclusions de deuxième phase ont été examinés. On a effectué des essais pour comparer les phénomènes microstructuraux se produisant lors du processus de déformation dynamique. L'introduction du rapport de croissance des vides ν a permis la description quantitative du processus de croissance des vides et l'estimation de l'effet de vitesse de déformation.
Abstract
Three steels based on ferritic matrix with silicates and sulphides as the second phase inclusions were examined. To compare the microstructural phenomena occuring during static and dynamic deformation process the tensile tests were carried out. Introduced void growth ratio υ allowed the void growth process to be described quantitatively and the strain rate effect to be estimated.
