Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer aus einer Nickel-Basis-Superlegierung bestehenden grossen Einkristallkomponente oder gerichtet erstarrten Komponente, wobei die Komponente zunächst in bekannter Art und Weise unter Ausbildung eines Dendriten aufweisenden Gefüges in Form gegossen und nachfolgend ein Lösungsglühen zur Homogenisierung des Gussgefüges der Komponente sowie eine zweistufige Ausscheidungswärmebehandlung durchgeführt werden. Zur Vermeidung von chemischen Inhomogenitäten und dadurch hervorgerufenen inneren Spannungen wird u.a. ein HIP-Verfahrensschritt mit einem Druck grösser 160 MPa im Anschluss an das Lösungsglühen durchgeführt.

Figure imgaf001
The invention relates to a method for producing a large consisting of a nickel-based superalloy large single crystal component or directionally solidified component, wherein the component first cast in a known manner to form a structure having dendrites in the form and then a solution annealing for homogenizing the cast structure of Component as well as a two-stage Ausscheidungswärmehandlung be performed. In order to avoid chemical inhomogeneities and internal stresses caused thereby, among other things, a HIP process step is carried out with a pressure of greater than 160 MPa following solution heat treatment.
