Description

Nickelbasissuperlegierung, geeignet auch zur additiven Fertigung, Verfahren und Produkt Nickel-based superalloy, also suitable for additive manufacturing, process and product
Die Erfindung betrifft eine Legierung, die besondere Vorteile bietet bei der additiven Fertigung von metallischen Bautei len, ein Verfahren und ein Produkt. The invention relates to an alloy which offers particular advantages in the additive manufacturing of metallic compo len, a method and a product.
Die Produkte sind vorzugsweise für den Einsatz in einer Strö mungsmaschine, vorzugsweise im Heißgaspfad einer Gasturbine vorgesehen . The products are preferably intended for use in a flow machine, preferably in the hot gas path of a gas turbine.
Additive Herstellungsverfahren umfassen beispielsweise als Pulverbettverfahren (PBF) das selektive Laserschmelzen (SLM) oder Lasersintern (SLS) oder das Elektronenstrahlschmelzen (EBM). Additive manufacturing processes include, for example, powder bed processes (PBF), selective laser melting (SLM) or laser sintering (SLS) or electron beam melting (EBM).
Weitere additive Verfahren sind beispielsweise „Directed Energy Deposition (DED) "-Verfahren, insbesondere Laserauf tragschweißen, Elektronenstrahl- oder Plasma-Pulverschweißen, Drahtschweißen, metallischer Pulverspritzguss, sogenannte „sheet lamination"-Verfahren, oder thermische Spritzverfahren (VPS LPPS, GDCS). Further additive processes are, for example, "Directed Energy Deposition (DED)" processes, in particular laser application welding, electron beam or plasma powder welding, wire welding, metallic powder injection molding, so-called "sheet lamination" processes, or thermal spray processes (VPS LPPS, GDCS).
Ein Verfahren zum selektiven Laserschmelzen ist beispielswei se bekannt aus EP 2601 006 Bl. A method for selective laser melting is known for example from EP 2601 006 Bl.
Additive Fertigungsverfahren (englisch: „additive manufac- turing") haben sich weiterhin als besonders vorteilhaft für komplexe oder filigran gestaltete Bauteile, beispielsweise labyrinthartige Strukturen, Kühlstrukturen und/oder Leicht- bau-Strukturen erwiesen. Insbesondere ist die additive Ferti gung durch eine besonders kurze Kette von Prozessschritten vorteilhaft, da ein Herstellungs- oder Fertigungsschritt eines Bauteils weitgehend auf Basis einer entsprechenden CAD- Datei und der Wahl entsprechender Fertigungsparameter erfol gen kann, und damit eine vorteilhafte Alternative - bei spielsweise gegenüber der konventionellen gießtechnischen Herstellung von Hochleistungsbauteilen mit den bekannten nachteiligen Prozessschritten - gegeben ist. Additive manufacturing processes have also proven to be particularly advantageous for complex or filigree components, for example labyrinth-like structures, cooling structures and / or lightweight structures. In particular, additive manufacturing is particularly short A chain of process steps is advantageous, since a manufacturing or manufacturing step of a component can largely take place on the basis of a corresponding CAD file and the selection of appropriate manufacturing parameters, and thus an advantageous alternative - for example to the conventional casting technique Production of high-performance components with the known disadvantageous process steps - is given.
Bislang gibt es bei mittels additiver Fertigung, insbesondere Laser beam powder bed fusion (LB-PBF) oder selektivem Laser schmelzen oder electron beam powder bed fusion (EB-PBF)) einer Nickelbasislegierung oft keinen rissfreien Strukturauf bau, so dass eine Optimierung diesbezüglich Gegenstand aktu eller Entwicklung ist. So far, there has often been no crack-free structure build-up with a nickel-based alloy using additive manufacturing, in particular laser beam powder bed fusion (LB-PBF) or selective laser melting or electron beam powder bed fusion (EB-PBF)), so that an optimization in this regard is currently the subject matter eller development is.
Nickelbasislegierungen des Standes der Technik sind bei spielsweise bekannt aus DE 102017 113780 Al, EP 3034 639 Al und DE 102016 221470 Al. Prior art nickel-based alloys are known, for example, from DE 102017 113780 Al, EP 3034 639 Al and DE 102016 221470 Al.
Diese Problematik wurde durch die vorliegende Erfindung auf gegriffen und eine Legierung mit engeren Spezifikationen von entscheidenden Elementen definiert, die den rissfreien oder für den bestimmungsgemäßen Betrieb tolerierbar rissarmen ad ditiven Strukturaufbau zur Folge hat. This problem was taken up by the present invention and an alloy with narrower specifications of decisive elements was defined, which results in an additive structure structure that is crack-free or tolerable for normal operation with few cracks.
Gerade bei additiven Fertigungstechnologien, insbesondere bei pulverbett-basierten Verfahren (PBF), treten prozessinhärent lokal sehr hohe Temperaturgradienten von teilweise mehr als 106 K/s auf, die die beschriebenen Heiß- oder Erstarrungsris se verursachen. Especially with additive manufacturing technologies, especially with powder bed-based processes (PBF), very high temperature gradients of sometimes more than 10 6 K / s occur locally, which cause the described hot cracks or solidification cracks.
Es ist die Aufgabe der Erfindung das oben genannte Problem zu lösen. It is the object of the invention to solve the above problem.
Die Aufgabe wird gelöst durch eine Legierung gemäß Anspruch 1, ein Verfahren gemäß Anspruch 3 und ein Produkt gemäß An spruch 7. The object is achieved by an alloy according to claim 1, a method according to claim 3 and a product according to claim 7.
Die Legierungselemente wurden gezielt angepasst, um rissfreie Proben fertigen zu können. The alloying elements were specifically adapted in order to be able to produce crack-free samples.
Dabei sind die Elemente Silizium (Si), Bor (B), Zirkon (Zr) und Hafnium (Hf) von besonderer Bedeutung und Kohlenstoff (C) ist ebenfalls zu beachten, aber vor allem Modifikationen von Hafnium (Hf) waren relevant. The elements silicon (Si), boron (B), zirconium (Zr) and hafnium (Hf) are of particular importance and carbon (C) should also be taken into account, but modifications of hafnium (Hf) were particularly relevant.
Die Erstarrungsrissneigung bei der Herstellung eines Produk tes aus der oder umfassend die beschriebene Legierung kann durch die vorliegende Erfindung vorteilhafterweise gemindert bzw. gänzlich vermieden werden. Dies beruht auf einer Redu zierung des Anteils an Flüssigphase/Eutektikum im Temperatur bereich von 1273K bis Solidustemperatur bei gleichzeitiger Einstellung eines kleineren Erstarrungsintervalls. The tendency to solidify cracks in the manufacture of a product from or comprising the alloy described can advantageously be reduced or entirely avoided by the present invention. This is based on a reduction in the proportion of liquid phase / eutectic in the temperature range from 1273K to solidus temperature with a simultaneous setting of a smaller solidification interval.
Auch durch die Reduzierung der g '-Solvustemperatur über die vorliegende Anpassung oder Wahl des Hf-Gehalts kann die Ver arbeitbarkeit verbessert bzw. die Rissneigung vorteilhafter weise reduziert werden. The processability can also be improved or the tendency to crack can advantageously be reduced by reducing the g 'solvus temperature by adapting or selecting the Hf content.
Die Fertigung erfolgt vorzugsweise mittels LB-PBF. Production is preferably carried out using LB-PBF.
