Abstract

La présente invention concerne des alliages renforcés par dispersion d'oxyde(s). Les alliages selon l'invention sont caractérisés en ce qu'ils contiennent 18-35 % de chrome; 3-7 % d'aluminium; 0,2-3,0 % d'un oxyde dispersoïde; 10-45 % de nickel et au moins 30 % de cobalt L'oxyde dispersoïde a, à 1000 degrés C, une énergie libre de formation au moins aussi grande que celle de l'aluminium. Ces alliages sont utilisables, dans des applications nécessitant de la résistance mécanique aux températures élevées et de la résistance à la corrosion à chaud.
