Abstract

L’invention concerne un alliage austénitique à base de nickel et à forte teneur en chrome, destiné à être utilisé à une température de service donnée entre 900°C et 1150°C. L’alliage comprend les composés suivants en pourcentage massique : - du chrome entre 40% et 45%, - du fer entre 10% et 14%, - du carbone entre 0,4% et 0,6%, - du titane entre 0,05 et 0,2%, - du niobium entre 0,5% et 1,5%, - au moins un élément réactif, choisi parmi les terres rares ou l’hafnium, entre 0,002% et 0,1%, - du silicium entre 0 et 1%, - du manganèse entre 0 et 0,5%, - du nickel pour faire la balance des composés de l’alliage,En outre, l’alliage présente une fraction molaire supérieure à 0,1% de carbo-nitrures secondaires riches en niobium et/ou en titane, après que la température de service lui ait été appliquée. L’invention concerne également un procédé de conception d’un tel alliage et un procédé de validation d’un tel alliage. Figure à publier avec l’abrégé : Pas de figure
