Definitions

  • the present invention relates to a nickel-base alloy which is substantially free of rhenium but at the same time achieves the creep resistance properties of the second-generation nickel-based superalloys and has a reduced density compared to comparable alloys.
  • nickel-base superalloys are used for example as blade materials, since these materials still have sufficient strength for the high mechanical loads even at high operating temperatures.
  • turbine blades are exposed in stationary gas turbines or jet engines in commercial aircraft exhaust gas flow at temperatures of up to 1500 ° C and are subject to very high mechanical loads due to centrifugal forces. Under these conditions, it is particularly important that the creep resistance of the material used meets the requirements.
  • turbine blades In order to increase creep resistance, turbine blades have also been produced monocrystalline for several decades in order to further improve creep resistance by avoiding grain boundaries.
  • the alloys In the nickel-base superalloys of the so-called second and third generation currently in use, the alloys usually have the chemical element rhenium in a proportion of three or six percent by weight, since rhenium further improves the creep resistance.
  • the EP 2 725 110 A1 a nickel-based alloy which is substantially free of rhenium and has a solidus temperature of higher than 1320 ° C, wherein at temperatures of 1050 ° C to 1100 ° C excretions of a y 'phase in a ⁇ matrix in a proportion of 40 to 50 Vol .-% are present, the ⁇ / ⁇ 'mismatch at temperatures of 1050 ° C to 1100 ° C in the range of -0.15% to -0.25% and the tungsten content in the ⁇ -matrix is greater than in the excreted y'-phases.
  • the alloy has the following chemical composition: aluminum of 11 to 13 at.%, Cobalt of 4 to 14 at.%, Chromium of 6 to 12 at.%, Molybdenum of 0.1 to 2 at.%, Tantalum from 0.1 to 3.5 at .-%, titanium from 0.1 to 3.5 at .-%, tungsten from 0.1 to 3 at .-%, and the balance nickel and unavoidable impurities.
  • the alloy should have the lowest possible density and good solution heatability, be economical and efficient to produce and monocrystalline or directionally solidified and compared to the in EP 2 725 110 A1 Reinforced rhenium-free nickel-based alloy improved with comparable creep resistance Have properties, in particular a lower density, a lower proportion of Resteutikikum and improved Amsterdamsglühbarkeit.
  • a nickel-base alloy may have the following chemical composition: aluminum of 4.1 to 7.7 wt%, cobalt of 0 to 16.8 wt%, chromium of 6 to 11.8 wt% , Molybdenum from 3.6 to 11.3 wt%, tantalum from 0 to 3.9 wt%, titanium from 0 to 3.6 wt%, tungsten from 0 to 11.3 wt% , Carbon of 0 to 0.05 wt.%, Phosphorus of 0 to 0.015 wt.%, Copper of 0 to 0.05 wt.%, Zirconium of 0 to 0.015 wt.%, Silicon of 0 to 0 , 01% by weight, sulfur from 0 to 0.001% by weight, iron from 0 to 0.15% by weight, manganese from 0 to 0.05% by weight, boron from 0 to 0.003% by weight , Hafnium from 0 to 0.15 wt .
  • a nickel-based alloy according to the present invention may have the following chemical composition: aluminum of 4.7 to 5.7% by weight, cobalt of 2.6 to 13.6% by weight, chromium of 6.3 to 7.3% by weight, molybdenum from 3.7 to 4.7% by weight, tantalum from 0 to 0.5% by weight, titanium from 2.8 to 3.6% by weight, tungsten from 7.4 to 8.4 wt .-%, carbon from 0 to 0.05 wt .-%, phosphorus from 0 to 0.015 wt .-%, copper from 0 to 0.05 wt .-%, zirconium from 0 to 0.015% by weight, silicon from 0 to 0.01% by weight, sulfur from 0 to 0.001% by weight, iron from 0 to 0.15% by weight, manganese from 0 to 0.05% by weight. %, Boron from 0 to 0.003% by weight, hafnium from 0 to 0.15% by weight, yttrium from
  • a nickel-based alloy according to the present invention may have the following chemical composition: aluminum of 5.0 to 5.4 wt .-%, cobalt of 2.9 to 13.3 wt .-%, chromium of 6.6 to 7% by weight, molybdenum from 4 to 4.4% by weight, tantalum from 0 to 0.2% by weight, titanium from 3.1 to 3.5% by weight, tungsten from 7.7 to 8.1% by weight, carbon from 0 to 0.05% by weight, phosphorus from 0 to 0.015% by weight, copper from 0 to 0.05% by weight, zirconium from 0 to 0.015% by weight.

  • a nickel-based alloy according to the present invention may have a cobalt content of less than 5% by weight, preferably less than 4% by weight. Since cobalt has a lower molar mass than nickel, a relatively low cobalt content has an advantageous effect on the overall density of the nickel-based alloy, and thus also on the total weight of the target component produced from this alloy.
  • the nickel-based alloy according to the invention may also have a cobalt content of greater than 11% by weight, preferably greater than 13% by weight.
  • a correspondingly high cobalt content has a positive effect on the segregation during solidification and the microstructural stability against the undesired formation of TCP phases.

  • the alloy elements are to be understood, the addition of which is not intended, but which can not be prevented for technical reasons or only with extremely great effort.
  • the following elements may still be present in the form of trace elements, the content of which is limited to the following ranges: bismuth from 0 to 0.00003% by weight, selenium from 0 to 0.0001% by weight, Thallium from 0 to 0.00005 wt%, lead from 0 to 0.0005 wt%, and tellurium from 0 to 0.0001 wt%.
  • alloy according to the invention in particular articles such as components of gas turbines, preferably turbine blades, and the like can be prepared, which may be monocrystalline or directionally solidified.
  • the attached figure shows a Larson-Miller plot to illustrate the creep resistance of the alloy according to the invention compared to known alloys.
  • alloy according to the invention was produced, the composition of which can be taken from the table below (alloy 1). Alloys 2 and 3 were chosen as comparison alloys, with the alloy 3 in the chemical composition essentially corresponding to that of the rhenium-containing material CMSX-4, and the alloy 2 corresponding to that in EP 2 725 110 A1 disclosed rhenium-free nickel base superalloy is. The components of the alloys are given in the table in weight percent (balance nickel and unavoidable impurities).

  • the alloy 1 according to the invention was produced in a columnar crystal structure on a laboratory Bridgman casting installation in a three-bar geometry.
  • the rods had a diameter of 12 mm each and a length of 180 mm each and showed a typical dendritic microstructure with a dendrite spacing of about 230 ⁇ m.
  • the proportion of residual eutectic is very low at 2.8% (alloys 2 and 3 have a residual eutectic of 6.5% and 9.0%, respectively).
  • alloy 1 has a typical fully cubic y'-phase morphology.
  • Alloy 1 (L1) according to the present invention has a creep resistance substantially equal to that of rhenium-free alloy 2 (L2), the creep resistances of these alloys being similar to the creep resistance of Alloy 3 (L3) corresponds to a second generation nickel base superalloy. In comparison to the alloys 2 and 3, however, the alloy 1 in particular has a lower density. Analysis of the microstructure of the inventive alloy 1 after creep revealed no TCP phase formation.
  • nickel-based superalloys can be provided by the teachings of the present invention which can dispense with the hard-to-obtain element rhenium but nevertheless provide high temperature mechanical properties such as creep resistance, such as known rhenium containing alloys, and also have lower density than known rhenium-containing and rhenium-free alloys.
  • alloy 1 may undergo one or both of the following precipitation heat treatments after solution annealing: Excretion heat treatment 1: temperature heating rate hold time 1000 ° C 4 K / min 1050 ° C 1K / min 1050 ° C 1 h 20 ° C rapid cooling Excretion heat treatment 2: temperature heating rate hold time 840 ° C 4 K / min 870 ° C 1K / min 870 ° C 24 hours 20 ° C rapid cooling
