Abstract

La présente invention concerne un matériau en acier permettant d'améliorer la résistance à la traction, lequel matériau comprend une première couche constituée d'un acier à très faible teneur en carbone et une seconde couche située de manière à être en contact avec la première couche et qui présente une première surface sur le côté opposé à la première couche, la seconde couche étant constituée d'une solution solide; l'azote étant dissous dans l'acier à très faible teneur en carbone; la seconde couche présentant une structure pratiquement identique à celle de la première couche.
