Abstract

Procédé d'évaluation de la fiabilité d'un acier en relation avec les inclusions de petite taille et de taille moyenne ainsi qu'avec les grosses inclusions, et acier de haute fiabilité obtenu selon ce procédé.Le procédé permet d'évaluer la fiabilité d'un acier en termes d'inclusions, et il se caractérise en ce qu'on évalue les inclusions dont la taille maximale est proche de 100 mum au plus par microscopie combinée à l'analyse statistique des valeurs extrêmes ; on évalue les inclusions dont la taille maximale est proche de 100 mum au moins par essai de détection de défauts par ultrasons à une fréquence dans la gamme de 5 à 25 MHz ; et l'on évalue la fiabilité de l'acier en fonction des résultats de l'analyse statistique des valeurs extrêmes appliquée aux résultats combinés de la microscopie et de l'essai de détection de défauts par ultrasons.
