Description
Die Erfindung betrifft ein Verfahren zur Herstellung wärmebehandelter Profile, deren Längsachse größer als deren Querachse ist, aus oxiddispersionsgehärteter Superlegierung auf Nickelbasis mit einem aus stengelförmigen, sich in Richtung der Längsachse erstreckenden Körnern gebildeten Grobgefüge durch Zonenglühung, bei der das Profil in Richtung der Längsachse kontinuierlich durch eine Aufheizzone bewegt wird und anschließend eine 10 bis 120 min, vorzugsweise 10 bis 60 min, dauernde isotherme Wärmebehandlung bei Temperaturen von 1150 bis 1280°C nach Hauptpatent . . . (Patentanmeldung P 40 04 471.8) erfolgt.The invention relates to a method for manufacturing heat-treated profiles whose longitudinal axis is larger than their Transverse axis is made of oxide dispersion hardened super alloy on a nickel base with a stalk-shaped, in Grains extending in the direction of the longitudinal axis Coarse structure through zone annealing, in which the profile in Direction of the longitudinal axis continuously through a Heating zone is moved and then a 10 to Isothermal for 120 minutes, preferably 10 to 60 minutes Heat treatment at temperatures from 1150 to 1280 ° C after Main patent. . . (Patent application P 40 04 471.8).
Gegenstand des Hauptpatents . . . (Patentanmeldung P 40 04 471.8) ist ein Verfahren zur Herstellung wärmebehandelter Profile und Formkörper aus oxiddispersionsgehärteten Superlegierungen auf Nickelbasis mit einem aus stengelförmigen Körnern gebildeten Grobgefüge, wobei die Profile bzw. Formkörper einer 5 bis 90 min dauernden Vorwärmebehandlung bei einer Temperatur von 950 bis 1180°C und anschließend einer 5 bis 120 min dauernden isothermen Wärmebehandlung bei einer Temperatur von < 1180 bis 1300°C unterworfen werden.Subject of the main patent. . . (Patent application P 40 04 471.8) is a manufacturing process heat-treated profiles and moldings Oxide dispersion hardened nickel-based superalloys with a rough structure formed from stem-shaped grains, the profiles or shaped bodies of a 5 to 90 min continuous preheating at a temperature of 950 up to 1180 ° C and then a 5 to 120 min isothermal heat treatment at a temperature of <1180 up to 1300 ° C.
In den im Hauptpatent . . . (Patentanmeldung P 40 04 471.8) behandelten Ausführungsformen ist u. a. erwähnt, daß anstelle der Vorwärmebehandlung des Profils auch eine Zonenglühung durchgeführt werden kann.In the main patent. . . (Patent application P 40 04 471.8) embodiments discussed is u. a. mentions that instead preheating the profile also zone annealing can be carried out.
Im Rahmen der konkreten Ausgestaltung des eingangs beschriebenen Verfahrens wird die Zonenglühung in der Weise durchgeführt, daß das Profil erfindungsgemäß mit einer Geschwindigkeit von 200 bis 2000 mm/h durch die Aufheizzone bewegt und dabei auf eine Temperatur von 950 bis 1150°C aufgeheizt wird, wobei der Temperatur/Weg-Gradient in der Aufheizzone 1 bis 20°C/mm beträgt. As part of the specific design of the method described at the outset, the zone annealing is carried out in such a way that the profile is moved through the heating zone according to the invention at a speed of 200 to 2000 mm / h and is heated to a temperature of 950 to 1150 ° C., whereby the temperature / displacement gradient in the heating zone is 1 to 20 ° C / mm.
Gegenüber dem im Hauptpatent . . . (Patentanmeldung P 40 04 471.8) beschriebenen Verfahren kann durch die erfindungsgemäße Zonenglühung ein relativ breiter Temperaturbereich benutzt werden, was für Profile mit großem Durchmesser von Vorteil ist.Compared to that in the main patent. . . (Patent application P 40 04 471.8) can be described by the method zone annealing according to the invention a relatively broad Temperature range can be used, what for profiles with large Diameter is an advantage.
Das im folgenden dargestellte Ausführungsbeispiel dient der Erläuterung der Erfindung.The embodiment shown below serves the Explanation of the invention.

wurde mit einer konstanten Vorschubgeschwindigkeit von 950 mm/h durch eine Aufheizzone bewegt, dabei auf eine Temperatur von 1095°C aufgeheizt und danach einer isothermen Wärmebehandlung bei einer Temperatur von 1200°C und 60 min Dauer unterzogen. Das feinkörnige Gefüge des stranggepreßten Rundprofils wird in ein gleichmäßiges Grobgefüge mit langgestreckten Körnern überführt. Die langgestreckten Körner besitzen eine durchschnittliche Länge von 20 mm, eine Breite von 0,5 mm und eine Dicke von 0,5 mm.was at a constant feed rate of 950 mm / h moved through a heating zone, thereby on a Temperature heated to 1095 ° C and then an isothermal Heat treatment at a temperature of 1200 ° C and 60 min Subjected to duration. The fine-grained structure of the extruded Round profile is in a uniform rough structure with elongated grains transferred. The elongated Grains have an average length of 20 mm, one Width of 0.5 mm and a thickness of 0.5 mm.
