Title (EN) A METHOD FOR HEAT TREATMENT OF A NICKEL BASE ALLOY SUCH AS ALLOY 282, SAID ALLOY AND COMPONENTS THEREOF
(FR) PROCÉDÉ DE TRAITEMENT THERMIQUE D'UN ALLIAGE À BASE DE NICKEL, TEL UN ALLIAGE 282, LEDIT ALLIAGE ET SES COMPOSANTS
Abstract:
(EN) The present disclosure relates to a method for heat treatment of an Alloy 282 which has been subjected to an initial solution annealing followed by cooling, the method comprising the steps of heating the Alloy 282 to a temperature between 954°C and 1010°C until the gamma prime (γ') phase is sufficiently disclosed, and cooling the Alloy 282 to a temperature a temperature sufficiently low, and at a cooling rate sufficiently high, to suppress gamma prime precipitation. Furthermore said alloy being heat treated according to the method and a component, a turbine exhaust case and a gas turbine engine made of said alloy are disclosed.
(FR) La présente invention concerne un procédé de traitement thermique d'un alliage 282 qui a été soumis à un recuit de solution initiale suivi d'un refroidissement. Le procédé comprend les étapes consistant à: chauffer l'alliage 282 à une température comprise entre 954 °C et 1010 °C jusqu'à ce que la phase gamma prime (γ') soit suffisamment exposée; et refroidir l'alliage 282 à une température suffisamment basse et à une vitesse de refroidissement suffisamment élevée pour supprimer la précipitation de gamma prime. La présente invention concerne également ledit alliage traité thermiquement d'après le procédé, ainsi qu'un composant, un carter d'échappement de turbine et un moteur à turbine à gaz constitués dudit alliage.
