Abstract

La présente invention concerne un article métallique incluant une composition métallique au moins partiellement thermotraitée, et un procédé de traitement de l'article métallique. Le procédé de traitement de l'article métallique peut inclure le chauffage de l'article métallique à une première température de maintien d'environ 690 °C, et le maintien de l'article métallique à la première température de maintien pendant au moins environ 10 heures. Le procédé peut également inclure le refroidissement de l'article métallique à partir de la première température de maintien jusqu'à une première température de refroidissement d'environ 65 °C ou moins. Le procédé peut en outre inclure le chauffage de l'article métallique à une deuxième température de maintien d'environ 615 °C, et le maintien de l'article métallique à la deuxième température de maintien pendant au moins environ 10 heures. Le procédé peut également inclure le refroidissement de l'article métallique à partir de la deuxième température de maintien jusqu'à une deuxième température de refroidissement d'environ 65 °C ou moins.
