Description

Die Erfindung betrifft eine Nickel-Chrom-Kobalt-Molybdän-Legierung mit ausgezeichneten Festigkeiten und Kriecheigenschaften sowie außergewöhnlicher Beständigkeit gegen Hochtemperaturkorrosion.The invention relates to a nickel-chromium-cobalt-molybdenum alloy having excellent strength and creep properties as well as exceptional resistance to high-temperature corrosion.

Durch die EP 0 358 211 B1 ist eine Nickel-Chrom-Molybdän-Kobalt-Legierung mit einer besonderen Karbidmorphologie bekannt geworden, die der Legierung eine bessere Zeitstandfestigkeit bei erhöhten Temperaturen verleiht. Die Legierung besteht (in Gew.-%) aus 15 bis 30% Chrom, 6 bis 12% Molybdän, 5 bis 20% Kobalt, 0,5 bis 3% Aluminium, bis 5% Titan, 0,04 bis 0,15% Kohlenstoff, bis 0,02% Bor, bis 0,5% Zirkonium, bis 5% Wolfram, bis 2,5% Niob oder Tantal, bis 5% Eisen, bis 0,2% Seltene Erdmetalle, bis 0,1% Stickstoff, bis 1% Kupfer, bis 0,015% Schwefel, bis 0,03% Phosphor und bis 0,2% Magnesium oder Kalzium, Rest außer Verunreinigungen Nickel.By the EP 0 358 211 B1 For example, a nickel-chromium-molybdenum-cobalt alloy having a particular carbide morphology has been disclosed which gives the alloy a better creep rupture strength at elevated temperatures. The alloy consists (in% by weight) of 15 to 30% chromium, 6 to 12% molybdenum, 5 to 20% cobalt, 0.5 to 3% aluminum, up to 5% titanium, 0.04 to 0.15% Carbon, up to 0.02% boron, up to 0.5% zirconium, up to 5% tungsten, up to 2.5% niobium or tantalum, up to 5% iron, up to 0.2% rare earth metals, up to 0.1% nitrogen, up to 1% copper, up to 0.015% sulfur, up to 0.03% phosphorus and up to 0.2% magnesium or calcium, balance except impurities nickel.

Wenngleich die Legierungen bis zu 2,5% Nb oder Ta enthalten können, beeinträchtigen diese Elemente die Beständigkeit der zyklischen Oxidation, was sich besonders stark bei gleichzeitiger Anwesenheit von Chrom und Aluminium auswirkt.Although the alloys can contain up to 2.5% Nb or Ta, these elements compromise cyclic oxidation resistance, which is particularly pronounced with the simultaneous presence of chromium and aluminum.

Derartige Legierungen werden seit vielen Jahrzehnten in der Praxis eingesetzt und sind unter der Bezeichnung „alloy 617” bekannt. Es hat sich herausgestellt, dass Bauteile, die aus derartigen Legierungen hergestellt wurden, im Temperaturbereich von 550 bis 850°C eine gewisse Neigung zu Spannungsrissen aufwiesen. Dies zeigte sich insbesondere an Schweißverbindungen dickwandiger Komponenten. Als Ursachen hierfür werden Eigenspannungen in Verbindung mit Karbidausscheidungen gesehen. Dies konnte ansatzweise, durch eine mehrstündige Wärmebehandlung bei ca. 1.000°C behoben werden, wobei eine derartige Wärmebehandlung in einigen Fällen nicht oder nur unter großen Schwierigkeiten durchgeführt werden konnte.Such alloys have been used for many decades in practice and are known as "alloy 617". It has been found that components made from such alloys have some tendency to stress cracking in the temperature range of 550 to 850 ° C. This was particularly evident in welded joints thick-walled components. The causes for this are seen as residual stresses in connection with carbide precipitations. This could be partially corrected by a heat treatment lasting several hours at about 1000 ° C, with such heat treatment could not be performed in some cases, or only with great difficulty.

Der Erfindung liegt die Aufgabe zugrunde, diese bekannte und auch bewährte Legierung durch gezielte Modifikation einzelner Legierungselemente so zu verbessern, dass die aufgezeigten Nachteile nicht mehr gegeben sind.The invention has for its object to improve this known and proven alloy by targeted modification of individual alloying elements so that the disadvantages are no longer given.

Von besonderem Vorteil ist, wenn die Gehalte an B und Nb wie folgt eingestellt werden:

  • – B 0,03–< 0,06%
  • – Nb 0,4–1,5%.
It is particularly advantageous if the contents of B and Nb are set as follows:
  • - B 0.03- <0.06%
  • - Nb 0.4-1.5%.

Der Mn-Gehalt beträgt vorteilhafterweise 0,05 bis ≤ 0,5%. Bedarfsweise kann die Legierung als weiteres Element W in Gehalten zwischen 0,02 und 2% enthalten.The Mn content is advantageously 0.05 to ≦ 0.5%. If desired, the alloy may contain as further element W in amounts between 0.02 and 2%.

Überraschenderweise hat sich gezeigt, dass durch gezieltes Zulegieren von Nb und B, die Ausscheidung von Chromkarbiden unterdrückt werden kann. Dadurch wird die Neigung zur Bildung von Spannungsrissen im Betrieb erheblich reduziert, so dass in den meisten Fällen auf eine Spannungsarmglühung verzichtet werden kann.Surprisingly, it has been found that by selective addition of Nb and B, the precipitation of chromium carbides can be suppressed. As a result, the tendency to form stress cracks during operation is significantly reduced, so that in most cases can be dispensed with a stress relief annealing.

Einem weiteren Gedanken der Erfindung gemäß genügt die erfindungsgemäße Legierung folgender Formel: X3 = 10–25, wobei X3 = 100· X1 / X2 und X1 = C + 5N und X2 = 0,5Ti + Nb + 0,5V ist. According to a further aspect of the invention, the alloy according to the invention satisfies the following formula: X3 = 10-25, where X3 = 100 × X1 / X2 and X1 = C + 5N and X2 = 0.5Ti + Nb + 0.5V.

Bedarfsweise kann die erfindungsgemäße Legierung zur Begünstigung der Nb-Karbidausscheidung einer Wärmebehandlung im Temperaturbereich zwischen 900 und 1.000°C unterzogen werden. Der Anteil an Niobkarbiden soll hierbei vorteilhafterweise > 10% sein. Durch gezielte Einstellung insbesondere der Gehalte an Nb und B kann nun eine derartige Wärmebehandlung ohne Schwierigkeiten durchgeführt werden.If desired, the alloy according to the invention may be subjected to a heat treatment in the temperature range between 900 and 1000 ° C. in order to promote Nb carbide precipitation. The proportion of niobium carbides should advantageously be> 10%. By targeted adjustment, in particular the contents of Nb and B, such a heat treatment can now be carried out without difficulty.

Durch den Erfindungsgegenstand wird eine hochwarmfeste Legierung für Betriebstemperaturen zwischen 500 und 1.200°C bereitgestellt.The subject invention provides a high temperature alloy for operating temperatures between 500 and 1200 ° C.
