(FR) ALLIAGE DE MULTIPLES ÉLÉMENTS PRINCIPAUX, À HAUTE TENEUR EN AZOTE, RÉSISTANT À LA CORROSION ET À ENTROPIE ÉLEVÉE
Resumo:
(EN) A multi-principal element, corrosion resistant alloy is disclosed. The alloy has the following composition in weight percent: Co about 13 to about 28 Ni about 13 to about 28 Fe+Mn about 13 to about 28 Cr about 13 to about 37 Mo about 8 to about 28 N about 0.10 to about 1.00. The alloy also includes the usual impurities found in corrosion resistant alloys intended for the same or similar use. In addition, one or both of W and V may be substituted for some or all of the Mo. The alloy provides a solid solution that is substantially all FCC phase, but may include minor amounts of secondary phases that do not adversely affect the corrosion resistance and mechanical properties provided by the alloy.
(FR) L'invention concerne un alliage de multiples éléments principaux résistant à la corrosion. L'alliage a la composition suivante, exprimée en pourcentage en poids : Co, d'environ 13 à environ 28 ; Ni, d'environ 13 à environ 28 ; Fe+Mn, d'environ 13 à environ 28 ; Cr, d'environ 13 à environ 37 ; Mo, d'environ 8 à environ 28 ; N, d'environ 0,10 à environ 1,00. L'alliage contient également les habituelles impuretés se trouvant dans les alliages résistants à la corrosion destinés à une utilisation identique ou similaire. De plus, W et/ou V peuvent remplacer tout ou partie de Mo. L'alliage fournit une solution solide qui est sensiblement entièrement en phase FCC mais qui peut contenir des quantités mineures de phases secondaires qui ne nuisent ni à la résistance à la corrosion, ni aux propriétés mécaniques de l'alliage.
