Description
Nickelbasislegierung für Hochtemperaturanwendungen und Nickel based alloy for high temperature applications and
Verfahren Procedure
Die Erfindung betrifft eine Legierung auf Nickelbasis für Hochtemperaturanwendungen, insbesondere für Gasturbinen, und ein Verfahren. The invention relates to a nickel-based alloy for high-temperature applications, in particular for gas turbines, and a method.
Bislang konnten mittels additiver Fertigung (SLM, SLS; mit tels Laser-, aber auch mittels Elektronenstrahlen (EBM) ) keine absolut rissfreien Komponenten erzeugt werden, so dass die Legierungsentwicklung weitergeführt worden ist. So far, no absolutely crack-free components could be produced using additive manufacturing (SLM, SLS; using laser, but also using electron beams (EBM)), so that the development of alloys has continued.
Diese Problematik wird aufgegriffen und eine Legierung mit Spezifikationen von entscheidenden Elementen definiert, die rissfreie Komponenten zur Folge hat. This problem is taken up and an alloy with specifications of decisive elements is defined, which results in crack-free components.
Es ist daher Aufgabe der Erfindung oben genanntes Problem zu lösen . It is therefore an object of the invention to solve the above problem.
Die Aufgabe wird gelöst durch eine Legierung gemäß Anspruch 1 und einem Verfahren gemäß Anspruch 2. The object is achieved by an alloy according to claim 1 and a method according to claim 2.
In den Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden kön nen, um weitere Vorteile zu erzielen. The subclaims list further advantageous measures which can be combined with one another as desired in order to achieve further advantages.
Die Legierungselemente wurden gezielt gewählt, um rissfreie Komponenten fertigen zu können. Dabei sind die Elemente Sili zium (Si), Bor (B) , Zirkon (Zr) und Hafnium (Hf) von besonde rer Bedeutung und Kohlenstoff (C) ebenfalls zu beachten. The alloying elements were specifically selected in order to be able to manufacture crack-free components. The elements silicon (Si), boron (B), zircon (Zr) and hafnium (Hf) are of particular importance and carbon (C) must also be taken into account.
Die Prozessbedingungen, insbesondere im EBM-Prozess, zeichnen sich durch eine hohe Bautemperatur von 1173K - 1373K über lange Zeiträume aus. In Abhängigkeit vom Bauteil sind mehrere Tage möglich. Hierbei handelt es sich um einzigartige Bedin gungen, die bei anderen bekannten Verfahren wie Gießen, Schmieden, Schweißen etc. nicht vorzufinden sind. Abgeleitet aus diesen Bedingungen wurden die Elemente Zirkon (Zr), Haf-
nium (Hf) und Silizium (Si) reduziert, um die Erstarrungs rissneigung der Legierung zu mindern bzw. gänzlich zu vermei den. Dies beruht auf einer Reduzierung des Anteils an Flüs- sigphase/Eutektikum im Temperaturbereich von 1173K bis Bau temperatur bei gleichzeitiger Einstellung eines kleineren Er starrungsintervalls . The process conditions, especially in the EBM process, are characterized by a high construction temperature of 1173K - 1373K over long periods. Depending on the component, several days are possible. These are unique conditions that cannot be found in other known processes such as casting, forging, welding, etc. The elements zirconium (Zr), nium (Hf) and silicon (Si) reduced to reduce the tendency of the alloy to solidify or to avoid it altogether. This is based on a reduction in the proportion of liquid phase / eutectic in the temperature range from 1173K to construction temperature with simultaneous setting of a smaller solidification interval.
Die Änderung der chemischen Zusammensetzung wird vorzugsweise ergänzt um Prozessparameter: Verfahrgeschwindigkeit, Verfahr strategie, Spurabstand, Leistung, Energiestrahl, Schicht dicke, Bautemperatur, ... bestimmt, die eine rissfreie Herstel lung ermöglichen. The change in the chemical composition is preferably supplemented by process parameters: travel speed, travel strategy, track spacing, power, energy beam, layer thickness, construction temperature, ..., which enable crack-free production.
Vorteile sind: The advantages are:
• Fertigung von Bauteilen ist rissfrei möglich, Bauteilinteg rität gewährleistet, Effizienzsteigerungen durch AM-Design möglich . • Manufacturing of components is possible without cracks, component integrity guaranteed, efficiency increases through AM design possible.
• Fertigung von hochwertigen Gasturbinenbauteilen mit neuer Legierung ist möglich, so dass zukünftige Bauteil-Anforde rungen abgedeckt werden können und ein Beitrag zur Effi zienzsteigerung von Gasturbinen geleistet wird. • Manufacture of high-quality gas turbine components with a new alloy is possible, so that future component requirements can be covered and a contribution can be made to increasing the efficiency of gas turbines.
