Title (EN) METHOD FOR PRODUCING AN ALLOY FOR A REFORMING TUBE
(FR) PROCÉDÉ DE FABRICATION D'UN ALLIAGE POUR TUBE DE REFORMAGE
Abstract: front page image
(EN) The invention relates to a microstructure of an alloy for a tube for reformers, having an austenitic matrix structure, characterised in that: i) primary micrometric precipitates in the form of M23C6-type carbides, where M=Fe, Ni or Cr, and/or M(C,N)-type carbides, where M==Nb or Ti, are formed during the solidification of the alloy; ii) secondary nanometric precipitates in the form of M23C6-type carbides, where M=Fe, Ni or Cr, and/or M(C,N)-type carbides, where M==Nb or Ti, are formed during the activation of the tube; and iii) between 0.1 and 0.3% of Ni16Si7Nb6-type intermetallic precipitates is formed during the use of the tube.
(FR) Microstructure d'un alliage pour tube pour reformeurs présentant une matrice austénitique caractérisée en ce que: i) des précipités primaires micrométriques sous la forme de carbures de type M23C6 avec M=Fe, Ni ou Cr et/ou de type M(C,N) avec M==Nb ou Ti se forment pendant la solidification de l'alliage : ii) des précipités secondaires nanométriques sous la forme de carbures de type M23C6 avec M=Fe, Ni ou Cr et de type M(C,N) avec M=Nb ou Ti se forment pendant la mise en service du tube; et iii) une quantité de précipités intermétalliques de type Ni16Si7Nb6 comprise entre 0,1 et 0,3 % se forme pendant l'utilisation du tube.
