  • Especially the superalloy consists of these elements.
  • The components of the invention can especially be part of a gas turbine, for example a turbine blade or vane, or as filler material, for example for laser welding of gas turbine components.
  • In the following one preferred embodiment of the invention is described. A superalloy was cast which has the composition given in Table 1.
  • TABLE 1
    Element wt %
    Co 4.12
    Cr 14.2
    Mo 0.96
    W 2.51
    Al 5.47
    Ta 10.1
    Hf 0.41
    C 0.04
    B 0.005
    Ni balance
  • Especially the superalloy comprises the elements Ni, Co, Cr, Mo, W, Al, Ta, Hf, C and B and very especially consists only of these elements.
  • In order to characterize the properties of the cast superalloy in Table 1 different experiments were conducted.
  • Solutioning experiments for 4 h at 1220, 1250, 1260, 1270 and 1300° C. followed by water quenching were done. At 1220° C. residual particles were seen and at 1250, 1260, 1270 and 1300° C. full solutioning without incipient melting was observed.
  • Further a heat treatment at 1250° C. for 8 h, 1100° C. for 4 h and 850° C. for 24 h was applied. SEM and TEM analysis showed a very regular microstructure with primary particles of ˜0.35 μm side length and a significant amount of secondary particles (see FIGS. 1 and 2).
  • No trace of TCP phases was found. The particle content was measured to be ˜60 vol %.
  • At this relatively high particle content it is usually difficult to obtain such a large heat treatment window, or, to include as much as 14% Cr without precipitation of brittle phases. Accordingly it was shown that this emphasis on Cr, Ta and Al
  • with at most moderate levels of other alloy elements provides a large heat treatment window and a good microstructural stability. Since Al is regarded as highly beneficial, Cr and Ta as beneficial, Mo and W as mildly detrimental (and Ti, Nb and V as detrimental) to oxidation resistance the composition in Table 1 will have a high oxidation resistance. With 14% Cr and a low level of the detrimental element Mo it will also have a high corrosion resistance.
  • With as much as 10% Ta supported by moderate levels of Mo and W is will also have a high strength, as Ta is a very potent strengthening element. Consequently it satisfies our requirements on high strength, high oxidation resistance, high corrosion resistance, microstructural stability and a large heat treatment window.
  • Table 2 shows a further preferred embodiment of the invention.

  • Especially the superalloy comprises the elements Ni, Co, Cr, Mo, W, Al, Ta, Hf, Zr, C and B and very especially consists only of these elements.
  • Most highly oxidation resistant alloys like e.g. CMSX-4 contain >5% Al and are cast with production processes to obtain <5 ppm S, and recently to levels as low as <0.5 ppm S.
  • The composition in Table 2 had an average content of sulphur (S) estimated to be ˜30 ppm, at which it should be severely detrimental, and the Al content is a comparatively moderate 4.5%. Cyclic oxidation tests on the superalloy in Table 2 nevertheless showed a stable response for 300 h under the severe test conditions of 1 h cycle time and 1100 C test temperature, which indicates an ability to form stable alumina, i.e. a high oxidation resistance. Accordingly it was shown that this emphasis on Cr, Ta and Al with at most moderate levels of other alloy elements provides a high oxidation resistance.

  • With as much as 10% Ta supported by moderate levels of Mo and W it will also have a high strength, as Ta is a very potent strengthening element.
  • Consequently it satisfies our requirements on high strength, high oxidation resistance, high corrosion resistance, microstructural stability and a large heat treatment window.
