Abstract
Description
Die Erfindung betrifft eine Titanaluminidlegierung.The invention relates to a titanium aluminide alloy.
Aus der JP-A-82 83 890 ist eine intermetallische Verbindung auf Ti-Al-Basis bekannt, deren Zusammensetzung beispielsweise Ti-44Al-8.5Nb unerwünschte Phasen enthält, wobei sowohl die ω- als auch die β*-Phase eine versprödende Wirkung erwarten läßt. Diese versprödende Wirkung ist für das angestrebte Ziel, nämlich bei einer hohen Betriebstemperatur im Einsatz dabei auch eine hohe Festigkeit zu bewahren, äußerst nachteilig.JP-A-82 83 890 is an intermetallic Ti-Al-based compound known, its composition for example Ti-44Al-8.5Nb unwanted phases contains, with both the ω and the β * phase can be expected to have an embrittling effect. This embrittling effect is for the desired goal namely in use at a high operating temperature maintaining high strength, extremely disadvantageous.
Es ist bekannt, Legierungen auf der Basis von Titanaluminiden für Zwecke einzusetzen, bei denen einerseits ein sehr geringes Gewicht und andererseits eine hohe Festigkeit des Werkstoffs erforderlich ist. Legierungen auf der Basis von Titanaluminiden ersetzen deshalb schon vielfach gewöhnliche Superlegierungen auf Nickelbasis, die gegenwärtig noch in einzelnen Komponenten, beispielsweise in Turbinen als Turbinenschaufeln, Verwendung finden. It is known to use alloys based on titanium aluminides use for purposes where on the one hand very light weight and high strength of the material is required. Alloys the base of titanium aluminides is therefore already replacing often common superalloys based on nickel, currently still in individual components, for example in turbines as turbine blades, use Find.
Die Legierungen auf der Basis von Titanaluminiden haben allerdings, obwohl sie an sich bei hoher Festigkeit ein geringes Gewicht aufweisen, nicht in jedem Falle alle die Eigenschaften, die die zuvor genannten Superlegierungen aufweisen und können bisher auch die durch diese Superlegierungen gesetzten hohen technischen Standards nicht vollständig erfüllen. Ein wesentlicher Nachteil der bisher bekannten Legierungen auf der Basis von Titanaluminiden ist der, daß sie ab einer Betriebstemperatur von 700° C eine deutliche Abnahme der Festigungseigenschaften aufweisen. Dies trifft insbesondere bei niedrigen Verformungsgeschwindigkeiten auf, die für eine Materialbeanspruchung unter Kriechbedingungen charakteristisch sind.Alloys based on titanium aluminides however, although they are inherently high strength light in weight, not all in all cases the properties of the aforementioned super alloys have and can so far also by this Super alloys set high technical standards not fully meet. A major disadvantage the previously known alloys based on Titanium aluminides is that they start at an operating temperature from 700 ° C a significant decrease in the strengthening properties exhibit. This is particularly true at low deformation speeds, which for a material stress under creep conditions are characteristic.
Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Legierung auf der Basis von Titanaluminiden bereitzustellen, die diese Nachteile nicht hat, d.h. eine Legierung, die ebenfalls eine hohe Temperaturfestigkeit aufweist, so daß diese auch geeignet ist, als Ersatz für Legierungen auf Nickelbasis zu dienen, wobei die erfindungsgemäße Legierung dennoch einfach und kostengünstig herstellbar und verhältnismäßig einfach bearbeitbar sein soll.It is therefore an object of the present invention to To provide an alloy based on titanium aluminides, which does not have these disadvantages, i.e. a Alloy, which also has high temperature resistance has, so that this is also suitable as a replacement for To serve nickel-based alloys, the invention Alloy nevertheless simple and inexpensive be producible and relatively easy to edit should.
Gelöst wird die Aufgabe gemäß der Erfindung durch eine Titanaluminidlegierung, deren Zusammensetzung Ti-45Al-xNb mit 5 ≤ x ≤ 10 Atom % und wahlweise bis zu 0,5 Atom % B und/oder C ist.The object is achieved according to the invention by a Titanium aluminide alloy, the composition of which is Ti-45Al-xNb with 5 ≤ x ≤ 10 atom% and optionally up to 0.5 atom % B and / or C.
Der Vorteil der erfindungsgemäßen Lösung besteht darin, daß, wie Versuche ergeben haben, signifikant höhere Festigkeiten bis in den Temperaturbereich von 900° C und höher, d.h. bei derartigen Betriebstemperaturen, denen die erfindungsgemäße Legierung ausgesetzt ist, erreicht werden können, und zwar gegenüber den bisher bekannten Legierungen auf der Basis von bisher verwendeten Titanaluminidgemischen.The advantage of the solution according to the invention is that that, as experiments have shown, significantly higher Strengths in the temperature range of 900 ° C and higher, i.e. at such operating temperatures that the alloy according to the invention is exposed can be compared to the previously known Alloys based on previously used titanium aluminide mixtures.
Ein weiterer wesentlicher Vorteil, der sich durch die erfindungsgemäß vorgeschlagene Lösung ergeben hat, ist der, daß der Oxidationswiderstand der erfindungsgemäß vorgeschlagenen Legierung sehr viel größer ist im Vergleich zu bisherigen Legierungsgemischen der gattungsgemäßen Art, d.h. insgesamt können die erfindungsgemäß vorgeschlagenen Legierungen aufgrund ihrer weit höheren Temperaturbeständigkeit gegenüber bisherigen Legierungen dieser Art zu technischen Lösungen verhelfen, zu denen bisher weder die Superlegierungen auf Nickelbasis noch die Legierungen auf der Basis von Titanaluminiden befähigt waren.Another major advantage, which is characterized by the has resulted in the solution proposed according to the invention that the oxidation resistance of the invention proposed alloy is very much larger in Comparison to previous alloy mixtures of the generic type Type, i.e. overall, the invention proposed alloys due to their wide range higher temperature resistance compared to previous ones Alloys of this kind help technical solutions, to which so far neither the superalloys Nickel based still the alloys based on Titan aluminides were capable.

Vorzugsweise wird die erfindungsgemäße Titanaluminidlegierung unter Verwendung gieß- oder pulvermetallurgischer Techniken hergestellt.The titanium aluminide alloy according to the invention is preferred using casting or powder metallurgical Techniques made.
Die Erfindung wird nun unter Bezugnahme auf zwei graphische Darstellungen beschrieben. Darin zeigen:
- Fig. 1
- die Variation des im Druckversuch gemessenen Fließ-Widerstandes über die Temperatur der erfindungsgemäßen Legierung sowie bekannter Legierungen auf der Basis von Titanaluminiden und
- Fig. 2
- das reziproke Aktivierungsvolumen (1/V) nach 1,25% plastischer Verformung unter Druck verschiedener erfindungsgemäßer Legierungen sowie bereits bekannter Legierungen auf der Basis von Titanaluminiden mit anderer Zusammensetzung.
- Fig. 1
- the variation of the flow resistance measured in the pressure test over the temperature of the alloy according to the invention and of known alloys based on titanium aluminides and
- Fig. 2
- the reciprocal activation volume (1 / V) after 1.25% plastic deformation under pressure of various alloys according to the invention and already known alloys based on titanium aluminides with a different composition.
Die voraufgeführten Figuren zeigen, daß die erfindungsgemäßen Legierungen sehr viel höhere Festigkeitswerte als konventionelle Legierungen haben. Gleichzeitig ist jedoch das reziproke Aktivierungsvolumen der erfindungsgemäßen Legierungen mit dem konventioneller Legierungen vergleichbar. Das bedeutet, daß größere Festigkeit von Legierungen, die Niob neben Titan und Aluminium enthalten, auch bei hohen Temperaturen und niedrigen Verformungsgeschwindigkeiten aufrechterhalten bleibt.The figures shown above show that the inventive Alloys have much higher strength values than conventional alloys. At the same time however, the reciprocal activation volume of the invention Alloys with the conventional alloys comparable. That means greater strength of Alloys containing niobium in addition to titanium and aluminum, even at high temperatures and low deformation speeds is maintained.
Die erfindungsgemäßen Legierungen mit der Zusammensetzung Ti-43Al-xNb mit 5 ≤ x 10 ≤ werden durch Verwendung herkömmlicher metallurgischer Gießmethoden oder durch an sich bekannte pulvermetallurgische Techniken erzeugt und können beispielsweise durch Warmschmieden, Warmpressen bzw. Warmstrangpressen und Warmwalzen bearbeitet werden.The alloys according to the invention with the composition Ti-43Al-xNb with 5 ≤ x 10 ≤ are made by use conventional metallurgical casting methods or by known powder metallurgical techniques are produced and can for example by hot forging, hot pressing or hot extrusion and hot rolling.
Neben den Basiskomponenten der Legierung aus Titan, Aluminium und Niob kann auch noch zur Erhöhung der Festigkeit bei hohen Arbeitstemperaturen der aus den Legierungen hergestellten Gegenstände, d.h. bis 900° C und darüber hinaus, Bor und/oder Kohlenstoff in Mengen von weniger als 0,5 Atom % hinzugefügt werden.In addition to the basic components of the titanium alloy, Aluminum and niobium can also increase the Strength at high working temperatures from the Articles made of alloys, i.e. up to 900 ° C and moreover, boron and / or carbon in quantities of less than 0.5 atomic% can be added.
