Definitions

  • the invention relates to the field of materials technology. It affects one Nickel-based superalloy, especially for the production of single crystal components (SX alloy) or components with a directionally solidified structure (DS alloy), such as blades for gas turbines.
  • SX alloy single crystal components
  • DS alloy directionally solidified structure
  • Such components made of nickel-based superalloys show high Temperatures have a very good material strength. This allows the Inlet temperature of gas turbines can be increased, increasing the efficiency of the Gas turbine rises.
  • Grain boundaries are areas of high local disorder of the crystal lattice, because in In these areas the neighboring grains collide and thus a certain one Disorientation exists between the crystal lattices.
  • Nitrogen is considered to be a harmful contaminant, one counteracting effect on the grain area and the formation of leads to non-metallic inclusions, for example titanium or tantalum nitrides. Grain defects can form on these inclusions (Metals Handbook, 10. Edition, 1990, ASM International, Vol. 1, p. 1000), which negatively affects the Properties of the alloys.
  • the invention tries to avoid all these disadvantages. You have the task based on a nickel-based superalloy (SX or DS alloy) for Manufacture to create single crystal components that differ from the known prior art due to a larger small angle grain size tolerance distinguished and yet very good fatigue properties has low number of cycles and high stress temperatures.
  • SX or DS alloy nickel-based superalloy
  • the essence of the invention is that the nickel-based superalloy essentially from (measured in% by weight) 3.0-13.0% Cr, 5.0-15.0% Co, 0-3.0% Mo, 3.5-9.5% W, 3.2-6.0% Al, 0-3.0% Ti, 2.0-10.0% Ta, 0-6.0% Re, 0.002-0.08% C, 0-0.04% B, 0-1.4% Hf, 0-0.005% Zr, 10-60 ppm N, balance nickel with There is contamination or that the nickel-based superalloy essentially from (measured in% by weight) 6.0-6.8% Cr, 8.0-10.0% Co, 0.5-0.7% Mo, 6.2-6.7% W, 5.4-5.8% Al, 0.6-1.2% Ti, 6.3-7.0% Ta, 2.7-3.2% Re, 0.02-0.04% C, 40-100 ppm B, 0.15-0.3% Hf, 15-50 ppm Mg, 0-400 ppm Y, 10-60
  • the advantages of the invention can be seen, inter alia, in that the controlled slight addition of nitrogen to DS or SX nickel based superalloys the carbides have a favorable block-like morphology exhibit. This allows the carbon content to be compared to that known State of the art can be increased without this with a deterioration of Fatigue behavior at low load cycles and high temperatures connected is. The increased carbon content has a positive impact on the Small angle grain boundaries.
  • Another advantage is that the block-like morphology of the Carbide the well-known phenomenon of long character-like carbides is eliminated, which oxidize very quickly along its length and therefore the Increase the degree of oxidation of the alloy, this long character-like carbides are often the places where there is a crack start shows.
  • the alloy according to the invention is thus characterized by an increased Oxidation resistance of the small-angle grain boundaries as well as improved longitudinal and transverse mechanical properties.
  • an advantage of the invention is that in contrast to the reactive elements such as Mg, Ce or other rare earths Nitrogen does not react with the mask shape during casting, so the Composition of the alloy over the length of the casting always is constant.
  • the nickel-based superalloy consists of (in% by weight) 6% Cr, 9% Co, 0.5% Mo, 8% W, 5.7% Al, 0.7% Ti, 3% Ta, 3% Re, 0.07% C, 0.015% B, 1.4% Hf, 0.005% Zr, 10-60ppm N, rest of nickel with impurities.

  • These alloys are in themselves known nickel-based superalloys, the composition of which by targeted addition of nitrogen was modified.
  • nickel-based superalloys described above a nitrogen content of 15 to 50 ppm, preferably 20 to 40 ppm. Above 60 ppm N, agglomerates of TiN particles form, which lead to a deterioration in properties, so this limit should not be exceeded.
  • the invention also relates to single crystal components, for example Buckets of gas turbines made from those described above Alloys according to the invention are produced.
