HOLD AND COOL PROCESS FOR SUPERALLOY JOINING
Ni base superalloys containing relatively large amounts of Al and/or Ti are known to be difficult to weld satisfactorily. As the Al and Ti content of the superalloy is increased to improve the strength, the weldability of the component is drastically reduced. It is concluded herein that reducing the...

| description | Ni base superalloys containing relatively large amounts of Al and/or Ti are known to be difficult to weld satisfactorily. As the Al and Ti content of the superalloy is increased to improve the strength, the weldability of the component is drastically reduced. It is concluded herein that reducing the gamma' phase improves weldability. A stepwise, controlled heating and cooling process is described to be used in cooperation with a welding process to reduce the gamma' present and thereby improve weldability.
Des superalliages à base de Ni contenant des quantités relativement importantes d'Al et/ou de Ti sont connus pour être difficiles à souder de façon satisfaisante. Alors que la teneur en Al et Ti du superalliage est augmentée pour améliorer la résistance, l'aptitude au soudage du composant est réduite de façon spectaculaire. On conclut ici que la réduction de la phase ' améliore la soudabilité. Un procédé de chauffage et de refroidissement contrôlé, par étapes, est décrit selon l'invention pour être utilisé en coopération avec un procédé de soudage pour réduire le ' présent et par là améliorer la soudabilité. |
