Definitions
- the invention relates to a creep-resistant, corrosion-resistant nickel-based alloy for Applications in high temperature technology.
- a nickel-based alloy with the short name NiCr 7030 accordingly DIN material number 2.4658 is considered heat-resistant and is used for heating conductors, Furnace components and the like used. Although such a material depends on Silicon and aluminum content has good oxidation resistance, this shows however low strength and low creep properties as well as high Creep values at operating temperatures around 1000 ° C.
- DE-C-4411228 discloses a high-temperature nickel base alloy become.
- This highly heat-resistant, oxidation-resistant, massively embroidered, warm and cold-formable nickel-based alloy essentially consists of (in Mass%) 0.001 to 0.15 carbon, 0.10 to 3.0 nitrogen, 25.0 to 30.0 chromium, more than 0.3 to 1.2 nitrogen, 0.001 to 0.01 boron, 0.01 to 0.5 yttrium, cerium, Lanthanum, hafnium and tantalum, individually or in combination, the rest nickel with one Proportion of at least 64.0%. Due to the carbon content one can Mixed crystal strengthening can be achieved, the main effective elements However, the above alloy in terms of high temperature properties Chromium and nitrogen. Chromium and nitrogen form chromium nitrides, which are the Improve creep rupture strength, with nitrogen additionally Solid crystal strengthening provides. With the alloy according to DE-C-4411228 significantly improved creep rupture strength and heat resistance values appear reachable.
- the object of the present invention is to overcome this defect eliminate and an improved nickel base alloy for To create high temperature applications.
- the elements of groups 4, 5 and 6 are in the essential titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V), niobium (Nb), tantalum (Ta), molybdenum (Mo) and tungsten (W) have a solid solution strengthening and have different activities related to non-metallic elements Carbon and nitrogen.
- Ti titanium
- Zr zirconium
- hafnium Hf
- V vanadium
- Nb tantalum
- Mo molybdenum
- W tungsten
- Ta and Nb form thermally highly stable Nitrides, on the other hand, is the nitrogen affinity of the strong carbide formers Mo and W low.
- a degree of solidification can be determined by the carbon content and the content of strong carbide formers can be adjusted. For example, if Low carbon content of the alloy, the strong carbide-forming elements increasingly installed in the crystal lattice of the mixed crystals and brace it.
- Another decisive advantage of the alloy according to the invention is that the elements mentioned above, in particular the elements Mo and W, shift the peritectic conversion of the II phase to higher temperatures by substitution of Cr atoms and thereby stabilize the II precipitates under conditions of use is effected.
- the addition of Mo does not result in volume changes even at high operating temperatures, which improves the high-temperature corrosion resistance because there is no initiation to flake off parts of the chrome spinel surface layer.
- Carbon with a content of more than 0.0015 wt .-% promotes the nitride and Carbonitride formation, but withdraws at a content of greater than 0.6 wt .-% Alloy too large amounts of carbide-forming elements, which one Counteracts matrix consolidation. Carbon contents of 0.16 are preferred up to 0.5% by weight.
- the ratio value nitrogen - to carbon content in the Alloy in the range of 0.5 to 5.5, preferably 1.0 to 4.0, optionally 1.0 up to 3.0, are particularly effective and stable Carbonitride precipitates formed and an efficient solid solution strengthening reached.
- Chromium contents in% by weight of 25 to 30 are preferred High temperature corrosion, it is important that the material at least 0.03 wt .-% Al and contains at least 0.4 wt .-% Si. Levels higher than 3.0% by weight of Al lead to disadvantageous excretion behavior, stress cracks and one Coarse grain formation and contents higher than 3.0% Si deteriorate the Hot formability of the alloy.
- the corrosion resistance at high temperatures can be increased if the material with elements of group 3 of the periodic table, that is Scandium (Sc), yttrium (Y) lanthanum (La) and lantanide up to a concentration of 0.15% by weight is alloyed.
- the contents are between 0.01 and 0.12% by weight. prefers.
- Nickel-based alloys with a composition according to the invention can with the help of pressure metallurgy, in which the liquid melt to solidification it is kept under high pressure (e.g. DESU process) or be produced by powder metallurgy.
- pressure metallurgy in which the liquid melt to solidification it is kept under high pressure (e.g. DESU process) or be produced by powder metallurgy.
- PM technology first a metal powder with the desired content of metallic elements prepared, then this powder via the gas phase at elevated temperature embroidered on and hot isostatically pressed.
- the cast or sintered block is usually deformed after one Homogenization of the material at 1250 ° C with forming at 1200 ° C. Grain sizes from 35 to 80 ⁇ m and nitride precipitates with a Diameters of 1 to 5 ⁇ m created in the material.
- the transition temperature of the II phase is determined by a Presence of elements of groups 4,5 and 6 (except Cr) increased.
- Tab. 1 are the determined dissolution and formation temperatures, the composition of the II phase and that of the - mixed crystal for a Mo-free Ni-Cr-N alloy and for those with a Mo content of 4 and 8% by weight and one with 4% by weight W specified.
- concentrations of 8% by weight Mo and 0.7% by weight N are for example, both temperature values for a ⁇ ⁇ ⁇ conversion above 1300 ° C.
- the II phase has a reduced chromium content of 45% by weight with a molybdenum concentration of 11% by weight. With a reduced nickel concentration, the ⁇ mixed crystal has increased chromium values of 29% by weight and a molybdenum content of 6.5% by weight. Influence of the molybdenum and tungsten content on the interval of the ⁇ + Cr 2 N transition temperature ⁇ T (dilatometer - examinations) Chemical composition [wt.
- Table 2 shows the chemical composition of the invention Alloys (alloys 1 to 5) and comparative alloys (alloys 6 to 9).
- Table 3 shows the mechanical properties of the alloys at 800 ° C. at 1000 ° C and at 1100 ° C.
- the resistance to high temperature corrosion was improved in the alloys according to the invention by approximately 16% (alloy 3 by more than 22%) compared to those in the prior art.

Die mit der Erfindung erreichten Vorteile sind im wesentlichen darin begründet, daß im Werkstoff bei Temperaturen bis 1200°C ein Korngrenzengleiten durch stabile Ausscheidungen in den Korngrenzenbereichen weitgehend verhindert und eine gesteigerte Mischkristallverfestigung erreicht werden. Weiters ist die Haftfestigkeit der Chrom-Spinelle oder dergleichen Schichten an der Oberfläche erhöht, wodurch eine verbesserte Hochtemperaturkorrosionsbeständigkeit der Teile gegeben ist.
γ + π → γ + ε entsprechend γ + Cr13Ni7N4 → γ + Cr2N
in Ni-Cr-N- Legierungen,welche mit einer Volumsänderung von etwa 1 x 10-3 % verbunden ist, wird beispielsweise, wie aus Tabelle 1 ersehen werden kann, durch eine Mo-Konzentration von 4 Gew.-% auf eine Temperatur von über 1210°C angehoben. Bei zyklischer Temperaturbeaufschlagung und Materialbeanspruchung sind durch den Zusatz von zum Beispiel Mo Volumsänderungen auch bei hohen Einsatztemperaturen nicht gegeben, was eine Verbesserung der Hochtemperaturkorrosions- Beständigkeit bewirkt, weil keine Initiation zum Abplatzen von Teilen der Chrom-Spinell-Oberflächenschicht vorliegt.
Mo + W / 2 = 3,0 bis 10, vorzugsweise 4,0 bis 8,0 aufweist.
