Definitions

  • the invention relates to the field of materials technology. It relates to a high-temperature iron-based alloy containing about 20% by weight of Cr and several parts by weight of Al and minor amounts of other constituents, and which have good mechanical properties and very good oxidation resistance at service temperatures of up to 1000 ° C.
  • ODS oxide-dispersion-strengthened, oxide dispersion strengthened
  • iron z. B. ferritic ODS FeCrAI alloys
  • They are due to their excellent mechanical properties at high temperatures preferred for thermally and mechanically highly stressed components, eg. B. for gas turbine blades used.
  • thermocouple protection tubes used, for example, in temperature control gas turbine sequential combustion gas turbines where they are exposed to extremely high temperatures and oxidizing atmospheres.
  • Table 1 sets forth the nominal chemical compositions (in weight%): Table 1: Nominal composition of known ODS-FeCrAlTi alloys component Fe Cr al Ti Si Addition of reactive elements (in the form of an oxide dispersion) alloy designation Kanthal APM rest 20.0 5.5 12:03 12:23 ZrO 2 -Al 2 O 3 MA 956 rest 20.0 4.5 0.5 - Y 2 O 3 -Al 2 O 3 PM 2000 rest 20.0 5.5 0.5 - Y 2 O 3 -Al 2 O 3
  • the materials mentioned have very high creep ruptures at very high temperatures and also excellent high-temperature oxidation resistance by forming an Al 2 O 3 protective film, as well as a high resistance to sulfidation and steam oxidation. They have strong directional characteristics. For example, in pipes, the creep strength in the transverse direction is only about 50% of the creep strength in the longitudinal direction.
  • document W02004104257 A1 discloses an iron-base alloy consisting of 10 to 25 wt% Cr, 1 to 10 wt% Al, 1.5 to 5 wt% Mo and balance Fe, for a jet pipe in cracking furnaces.
  • This jet tube has a creep rupture strength over 100,000 hours at a temperature of 1100 ° C and a relinquishment of 2.2 MPa.
  • the aim of the invention is to avoid the mentioned disadvantages of the prior art.
  • the invention is based on the object to develop a suitable material for the above applications, which is less expensive than the known from the prior art material PM 2000, but has at least as good oxidation resistance.
  • the material according to the invention should be readily thermoformable and should have better mechanical properties than z.
  • KANTHAL APM which is used for heating elements.
  • the alloy preferably contains 5 to 6% by weight of Al, particularly preferably 5.5 to 6% by weight of Al. This forms a good Al 2 O 3 protective film on the material surface which enhances the high temperature oxidation resistance.
  • the material according to the invention particularly preferably comprises 2-4% by weight of Mo and / or 2-4% by weight of Ta.
  • Ta, Zr and B are elements which act as precipitation strengthening agents.
  • alloys were prepared by arc melting the specified elements and then rolled at temperatures of 900-800 ° C before, among other things, the tensile specimens were prepared.
  • Fig. 1 For the alloys listed, the weight change at 1100 ° C over time over a period of 12 hours is shown.
  • the alloy 2008 eg with 4% Mo and 5.5% Al
  • Fig. 2 For the specified alloys, the weight change at 1000 ° C in air over time over a period of 1000 hours is shown. It can be seen that the alloys 2014 and 2013 have a significantly improved oxidation behavior. After 1,000 hours of aging in air at 1000 ° C, the weight changes in the two alloys only one-third (alloy 2013) to less than half (alloy 2014) of the weight change compared to the well-known alloy PM 2000. Apparently affects a combination of Mo and Ta in equal proportions particularly good on the oxidation behavior at 1000 ° C from. In particular, Ta increases the activity of Al in the given range and improves the oxidation resistance.
  • FIGS. 3 to 5 the results of tensile tests in the temperature range from room temperature to 1000 ° C are shown.
  • Fig. 3 shows the dependence of the tensile strength on the temperature of the specified materials. At room temperature, the values of the investigated materials are relatively close to each other. Some materials (eg alloys 2007 and 2013) are stronger at room temperature than those known from the prior art Materials), in others there are hardly any differences to the well-known alloys PM 2000 and Kanthal APM.
  • the tensile strength values remain approximately constant as a function of the temperature, then they drop markedly as expected.
  • the investigated alloys invariably have higher tensile strengths than Kanthal APM and somewhat lower tensile strengths than PM 2000. However, this is associated with the excellent oxidation behavior of these alloys at 1000 ° C (see Fig. 2 ), then these are very good property combinations.
  • Fig. 4 the dependence of the yield strength on the temperature is shown. The tendency corresponds approximately to the course of the tensile strength according to Fig. 3 ,
  • Fig. 5 finally shows the dependence of the elongation at break of the temperature in the range from room temperature to 1000 ° C.
  • the elongation at break values in the range from RT to 400 ° C. are approximately constant, at 600 ° C. the maximum value is twice the value compared with RT, then the elongation at break values decrease with increasing temperature until at 1000 ° C. approx. half of the value is reached at RT.
  • the increase in ductility of PM 2000 at about 600 ° C is due to the softening of the material.
  • novel materials can also be hot rolled well, they have a good plastic deformability.
  • thermocouple thermowell They are very useful as a thermocouple thermowell, the latter being used, for example, in gas turbines with sequential combustion for temperature control where they are exposed to oxidizing atmospheres.
  • the alloys according to the invention have a very high oxidation resistance at 1000 ° C. They have better mechanical properties than the Kanthal APM alloy known from the prior art. Although the strength values of the alloys according to the invention are slightly lower than those of the alloy PM 2000 at high temperatures, the ductility is considerably better for this purpose. Moreover, at 1000 ° C., the oxidation resistance is more than twice as high as in PM 2000. Since the alloys according to the invention are also cheaper than PM 2000 (cheaper components, easier production), they are outstandingly suitable as a replacement for PM 2000 for the fields of application described above.
