Description

Beschreibung description
Nickelbasislegierung, Pulver, Verfahren und Bauteil Nickel-based alloy, powder, process and component
Die Erfindung betrifft eine Nickelbasislegierung nach Pa tentanspruch 1, ein Pulver nach Patentanspruch 7, sowie ein Verfahren nach Patentanspruch 9 und ein Bauteil nach Pa tentanspruch 12. The invention relates to a nickel-based alloy according to patent claim 1, a powder according to patent claim 7, as well as a method according to patent claim 9 and a component according to patent claim 12.
Nickelbasislegierungen weisen eine hohe Korrosionsfestigkeit und eine hohe Temperaturfestigkeit, insbesondere eine hohe Kriechfestigkeit bei hohen Temperaturen auf. Legierungen, die letztere Eigenschaften aufweisen, werden auch als sogenannte Superlegierungen auf Nickelbasis bezeichnet. Diese Legierun gen finden insbesondere im Triebwerksbau oder in Turbinen zur Energieerzeugung Anwendung. In der Regel werden die Bauteile, die aus den beschriebenen Nickelbasislegierung bestehen, durch ein Gießverfahren oder durch Sinterverfahren herge stellt. Ein Beispiel für eine entsprechende Legierung wird in der DE 102017 007 106 B4 gegeben. Nickel-based alloys have high corrosion resistance and high temperature resistance, in particular high creep resistance at high temperatures. Alloys with the latter properties are also referred to as so-called nickel-based superalloys. These alloys are used in particular in engine construction or in turbines for generating energy. As a rule, the components, which consist of the nickel-based alloys described, are manufactured using a casting process or a sintering process. An example of a corresponding alloy is given in DE 102017 007 106 B4.
Zunehmend finden jedoch auch additive Herstellungsverfahren unter Verwendung von Nickelbasislegierung Anwendung. Eine hierfür gut geeignete Legierung wird in der W02018/083065A1 beschrieben. Ausgehend von dieser Legierung ist es die Aufga be der Erfindung, die Kriechfestigkeit weiter zu erhöhen und dabei die Mikrorissbildung auf einem niedrigen Niveau zu be wahren oder diese auch noch zu reduzieren. However, additive manufacturing processes using nickel-based alloys are also increasingly being used. An alloy that is well suited for this is described in WO2018 / 083065A1. Starting from this alloy, it is the task of the invention to further increase the creep strength while maintaining the microcrack formation at a low level or even reducing it.
Die Lösung der Aufgabe besteht in einer Nickelbasislegierung nach Patentanspruch 1, sowie in einem Pulver nach Patentan spruch 7, in einem Verfahren nach Patentanspruch 9 und in ei nem Bauteil nach Patentanspruch 12. The object is achieved in a nickel-based alloy according to claim 1, as well as in a powder according to claim 7, in a method according to claim 9 and in a component according to claim 12.
Die erfindungsgemäße Nickelbasislegierung weist dabei zumin dest folgende Legierungselemente in Gew. % auf: The nickel-based alloy according to the invention has at least the following alloy elements in% by weight:
Kobalt (Co) 10,3 - 10,7 Chrom (Cr) 9,8 - 10,2 Wolfram (W) 9,3 - 9,7, Aluminium (Al) 5,2 - 5,7, Hafnium (Hf) 1,8 - 2,2, Tantal (Ta) 1,9 - 2,1, Molybdän (Mo) 0,4 - 0,6, wobei der Rest Nickel sowie Verunreinigungen umfasst. Cobalt (Co) 10.3-10.7 Chromium (Cr) 9.8-10.2 Tungsten (W) 9.3 - 9.7, aluminum (Al) 5.2 - 5.7, hafnium (Hf) 1.8 - 2.2, tantalum (Ta) 1.9 - 2.1, molybdenum ( Mo) 0.4-0.6, the remainder comprising nickel and impurities.
Gegenüber dem oben beschriebenen Stand der Technik unter scheidet sich die vorliegende Legierung insbesondere darin, dass der Anteil an Hafnium insofern erhöht wurde, dass dieser nun zwischen 1,8 und 2,2 Gewichtsprozent liegt. Die Erstar rungsrissneigung der Legierung wurde hierdurch merklich ge mindert bzw. unter Anpassung der Prozessparameter vollständig verhindert. Die gezielte Erhöhung des Anteils an Hafnium ver bessert zusätzlich die mechanischen Eigenschaften durch die Erhöhung des Anteils an sogenannten g' Phasen im Gegensatz zu Legierungen mit einem niedrigeren Anteil an Hafnium. Auch der Anteil an Tantal liegt gegenüber dem Stand der Technik in ei nem leicht erhöhten Bereich. Compared to the prior art described above, the present alloy differs in particular in that the proportion of hafnium has been increased to the extent that it is now between 1.8 and 2.2 percent by weight. The tendency of the alloy to solidify was thereby noticeably reduced or completely prevented by adapting the process parameters. The targeted increase in the proportion of hafnium also improves the mechanical properties by increasing the proportion of so-called g 'phases in contrast to alloys with a lower proportion of hafnium. The proportion of tantalum is also in a slightly higher range than in the prior art.
In einer bevorzugten Ausgestaltungsform der Erfindung wird der jeweilige Anteil der Legierungselemente noch einmal in einem engeren prozentualen Bereich angegeben und umfassen zu mindest wie folgt: In a preferred embodiment of the invention, the respective proportion of the alloying elements is specified again in a narrower percentage range and include at least the following:
Kobalt (Co) 10,55 - 10,65, Chrom (Cr) 9,8 - 10,9, Wolfram (W) 9.35 - 9,45, Aluminium (Al) 5.35 - 5,45, Hafnium (Hf) 1,85 - 1,95, Tantal (Ta) 1,95 - 2,05, Molybdän (Mo) 0,4 - 0,6, wobei der Rest Nickel sowie Verunreinigungen umfasst. Cobalt (Co) 10.55 - 10.65, chromium (Cr) 9.8 - 10.9, tungsten (W) 9.35 - 9.45, aluminum (Al) 5.35 - 5.45, hafnium (Hf) 1, 85 - 1.95, tantalum (Ta) 1.95 - 2.05, molybdenum (Mo) 0.4 - 0.6, with the remainder comprising nickel and impurities.
In diesem engeren Bereich liegt auch eine konkrete Legie rungszusammensetzung, die als besonders vorteilhaft getestet ist. Dieser weist nach Messung der Zusammensetzung folgende Einzelanteile der entsprechenden Legierungsbestandteile auf: Kobalt (Co) 10,6, Chrom (Cr) 9.8, Wolfram (W) 9.4, In this narrower range there is also a specific alloy composition that has been tested to be particularly advantageous. After measuring the composition, this shows the following individual proportions of the corresponding alloy components: Cobalt (Co) 10.6, Chromium (Cr) 9.8, Tungsten (W) 9.4,
Aluminium (Al) 5.4, Aluminum (Al) 5.4,
Hafnium (Hf) 1.9, Tantal (Ta) 2,0, Hafnium (Hf) 1.9, tantalum (Ta) 2.0,
Molybdän (Mo) 0,5, Kohlenstoff (C) 0,06 wobei der Rest Nickel sowie Verunreinigungen ist. Molybdenum (Mo) 0.5, carbon (C) 0.06 with the remainder being nickel and impurities.
Bei dieser speziellen Legierung hat sich herausgestellt, dass die Neigung zu Mikrorissen besonders gering ist und eine Hochtemperatur-Kriechfestigkeit zum Tragen kommt, die gegen über dem Stand der Technik deutlich verbessert ist. In the case of this special alloy, it has been found that the tendency to micro-cracks is particularly low and that high-temperature creep resistance comes into play, which is significantly improved compared to the prior art.
Die bisher beschriebenen Legierungszusammensetzungen sind so formuliert, dass neben den Verunreinigungen auch noch weitere Bestandteile in geringen Umfang vorhanden sein können. Es hat sich dabei als vorteilhaft herausgestellt, einen Kohlenstoff anteil zu wählen, der nach Gewichtsprozent zwischen 0,04 und 0,08 liegt. The alloy compositions described so far are formulated in such a way that, in addition to the impurities, other constituents can also be present to a small extent. It has been found to be advantageous to choose a carbon content that is between 0.04 and 0.08 in percent by weight.
Ferner ist es zweckmäßig, dass die Legierung Bor und/oder Zirkon in geringen Bestandteilen umfasst, die bevorzugt zwi schen 0,0025 und 0,01 Gewichtsprozent liegen. Furthermore, it is expedient that the alloy comprises boron and / or zirconium in small components, which are preferably between 0.0025 and 0.01 percent by weight.
Die Anteile weiterer Legierungsbestandteil von untergeordne ter Bedeutung, die auch als Verunreinigungen angesehen werden können, nämlich Silizium, Mangan, Phosphor, Schwefel, Titan, Bor, Zirkon, Eisen, Kupfer, Silber, Blei, Selen, Bismut und Magnesium sollten jeweils weniger als 0,1 Gew. %. Insbesonde re weniger als 0,05 Gew. %, bei Silizium bevorzugt weniger als 0,02 Gew% betragen. The proportions of other alloy components of subordinate importance that can also be viewed as impurities, namely silicon, manganese, phosphorus, sulfur, titanium, boron, zirconium, iron, copper, silver, lead, selenium, bismuth and magnesium, should each be less than 0 , 1% by weight. In particular less than 0.05% by weight, preferably less than 0.02% by weight in the case of silicon.
Ein weiterer Bestandteil der Erfindung ist ein Pulver das ei ne Legierung nach einem der Patentansprüche 1-6 umfasst. Mit dem Begriff „umfasst" ist damit gemeint, dass dieses Pulver zum wesentlichen aus der besagten Legierung besteht, dass es aber auch noch Zusatzstoffe aufweisen kann, die ein additives Herstellungsverfahren positiv beeinflussen. Hierbei kann es sich um bestimmte Bindemittel oder Trennstoffe handeln. Das bedeutet, dass sowohl die Legierung an sich als auch das hie raus resultierende Pulver insbesondere zur Herstellung von Bauteilen mit einem additiven Fertigungsverfahren einsetzbar ist. Another component of the invention is a powder which comprises an alloy according to any one of claims 1-6. The term “comprises” means that this powder consists essentially of the said alloy, that it but can also contain additives that have a positive effect on an additive manufacturing process. These can be specific binders or release agents. This means that both the alloy itself and the powder resulting from it can be used, in particular, for the production of components with an additive manufacturing process.
In diesem Zusammenhang ist auch ein Verfahren zur Herstellung eines Bauteils Bestandteil der Erfindung, das unter Verwen dung einer Legierung gemäß des Patentanspruchs 1-6 bzw. eines Pulvers nach den Patentansprüchen 7 oder 8 erfolgt. Dabei ist das Verfahren bevorzugt ein additives Herstellungsverfahren, insbesondere ein Laser-Sinterverfahren oder ein selektives Laseraufschmelzverfahren, z. B. LPBF. In this context, a method for producing a component is also part of the invention, which is carried out using an alloy according to claims 1-6 or a powder according to claims 7 or 8. The process is preferably an additive manufacturing process, in particular a laser sintering process or a selective laser melting process, e.g. B. LPBF.
Ein weiterer Bestandteil der Erfindung besteht in einem Bau teil, das eine Legierung nach einem der Patentansprüche 1-6 oder ein Pulver nach einem der Ansprüche 7 oder 8 umfasst, wobei unter Vernachlässigung von geringfügigen Additiven das Bauteil aus dieser Legierung besteht. Unter dem Begriff Bau teil ist hierbei auch ein Halbzeug zu verstehen, dass durch weitere Verfahrensschritte in ein weiteres Bauteil integriert sein kann und somit dann im Endmontage-Zustand auch weitere Materialbestandteile aufweisen kann. Another component of the invention consists in a construction part which comprises an alloy according to one of claims 1-6 or a powder according to one of claims 7 or 8, the component being made of this alloy, neglecting minor additives. The term component here is also to be understood as a semi-finished product that can be integrated into a further component through further process steps and thus can then also have further material components in the final assembly state.
Besonders vorteilhaft ist die Anwendung der Legierung, des Pulvers des Verfahrens und somit auch des Bauteils in Turbi nen die zum Erzeugen von elektrischen Strom dienen. Insbeson dere in Gasturbinenbauteilen. Grundsätzlich kann die Erfin dung auch Anwendung in Turbinen finden, die zum Antrieb von Fortbewegungsmittel dienen, insbesondere auch in Flugzeugtur binen. It is particularly advantageous to use the alloy, the powder of the process and thus also the component in turbines which are used to generate electrical power. Especially in gas turbine components.
