| description | A process is described that includes forming a metal alloy component having a pre-specified three dimensional geometry for use in a nuclear reactor by an additive manufacturing process followed by annealing the formed component at a first annealing temperature within the alpha temperature range of the phase diagram for the metal alloy. A second annealing step at a second annealing temperature lower than the first annealing temperature may be added. Alternatively, annealing may be at an annealing temperature in the alpha+beta temperature range of a phase diagram for the metal alloy, followed by a second anneal in the alpha temperature range of the phase diagram for the metal alloy.
L'invention concerne un procédé qui comprend la formation d'un constituant d'alliage métallique ayant une géométrie tridimensionnelle pré-spécifiée, destiné à être utilisé dans un réacteur nucléaire, par un procédé de fabrication additive suivi du recuit du constituant formé à une première température de recuit au sein de la plage de température alpha du diagramme de phase pour l'alliage métallique. Une seconde étape de recuit à une seconde température de recuit inférieure à la première température de recuit peut être ajoutée. En variante, le recuit peut être effectué à une température de recuit dans la plage de température alpha+beta d'un diagramme de phase pour l'alliage métallique, suivi d'un second recuit dans la plage de température alpha du diagramme de phase pour l'alliage métallique. |
