Abstract

Alliage d'acier de haute résistance et de haute ténacité à la rupture consistant essentiellement, en pourcentage en poids, en: C: 0,2-0,33; Mn: 0,20 max; Si: 0,1 max; P: 0,008 max; S: 0,004 max; Cr: 2-4; Ni: 10,5-15; Mo: 0,175-1,75; Co: 8-17; Ce: quantité efficace-0,030; La: quantité efficace-0,01; Fe: le solde; ainsi qu'un article fabriqué à partir de cet alliage. Une quantité petite mais efficace de calcium peut être présente dans cet alliage en substituion à tout ou partie du cérium et du lanthane. L'alliage est un alliage d'acier martensitique durcissable par vieillissement qui offre une combinaison unique de résistance à la traction et de ténacité à la rupture. L'alliage possède d'excellentes propriétés mécaniques lorsqu'il est durci par un traitement thermique sous vide avec refroidissement par gaz inerte et possède une faible température de transition de résilience.
