Definitions

  • the invention relates to a method for producing a heavy-duty component of an ⁇ + ⁇ -titanium aluminide alloy for reciprocating engines and gas turbines, in particular aircraft engines.
  • TiAl-based alloys belong to the group of intermetallic materials which have been developed for applications in the field of application temperatures of superalloys. Due to its low density of about 4 g / cm 3 , this material offers considerable potential for saving weight and reducing the loads on moving components, eg blades and disks of gas turbines or components of piston engines, at temperatures up to approx. 700 ° C. State of the art is the investment casting of z. B. turbine blades for aircraft engines. For applications with higher load such. As in high-speed turbines for novel geared turbofan aircraft engines, the properties of the cast structure are no longer sufficient.
  • thermomechanical treatment by means of plastic forming with a defined degree of deformation and subsequent heat treatment, the static and dynamic properties of TiAl alloys can be increased to the required values.
  • TiAl alloys are not conventionally forgeable because of their high resistance to deformation. Therefore, the forming processes at high temperatures in the region of the ⁇ + ⁇ or ⁇ -phase region must be carried out in a protective atmosphere at low forming speeds. In order to achieve the desired final geometry of the forging part id usually several consecutive forging steps are required.
  • the invention is thus the task of specifying a method for producing a highly loaded component of an ⁇ + ⁇ -Titanaluminid-alloy, which is easier to implement compared to previously known methods.
  • the inventive method is characterized by a single-stage, isothermal forming process of the component in the ⁇ -phase region at slow forming speed, wherein a specific TiAl alloy is used, which makes it possible to stabilize the component in the ⁇ -phase region, so that there is the forming can.
  • the alloy contains a corresponding proportion of at least one ⁇ -phase stabilizing element selected from Mo, V, Ta, Cr, Mn, Ni, Cu, Fe or Si, although mixtures thereof can also be used.
  • ⁇ -phase stabilizing elements Mo, V or Ta are used, which can be used individually or as a mixture.
  • the content of the ⁇ -phase stabilizing element is preferably 0.1-2%, in particular 0.8-1.2%. This in particular when Mo, V and / or Ta are used, since they have a particularly high stabilizing property and therefore their content can be kept relatively low.
  • the forming temperature in the ⁇ -phase range is preferably 1070-1250 ° C., wherein as described, the deformation takes place isothermally, that is, that the forming tools are kept at the forming temperature so as not to leave the required narrow temperature window.
  • the logarithmic deformation rate is 10 -3 s -1 to 10 -1 s -1 .
  • the preform used has a volume distribution which varies over the longitudinal axis, ie that a given three-dimensional basic shape is already given, from which the finished component is forged by the single-stage forming according to the invention.
  • This preform is preferably produced by casting, metal injection molding (MIM) or additive processes (3D printing, laser deposition welding, etc.) or a combination of the abovementioned possibilities.
  • forming tools are preferably used from a highly heat-resistant material, preferably from a Mo alloy.
  • the tools are protected during the forming process by an inert atmosphere against oxidation.
  • they are preferably actively heated, for example inductively or by resistance heating.
  • the preform is heated before the forming process, for example in an oven, inductively or by resistance heating.
  • the deformation is followed by a heat treatment of the formed component in order to set the required performance properties and to convert the ⁇ -phase, which is favorable for the transformation, into a fine-lamellar ⁇ + ⁇ -structure by means of a suitable heat treatment.
  • the heat treatment may comprise a recrystallization annealing at a temperature of 1230-1270 ° C.
  • the holding time during the recrystallization annealing is preferably 50-100 min.
  • the recrystallization annealing takes place in the region of the ⁇ / ⁇ transformation temperature. If, as is further provided according to the invention, after the recrystallization annealing, the component is cooled to a temperature of 900-950 ° C. in 120 s or faster, small ⁇ finite pitches of the ⁇ + ⁇ phase occur.
  • a second heat treatment step follows, in which the component is first cooled to room temperature and then heated to a stabilizing or relaxation temperature of 850-950 ° C.
  • the stabilization and relaxation temperature of 850 ° -950 ° C. can also be gone directly from the temperature of 900-950 ° C. which has been reached rapidly after the recrystallization annealing as described above.
  • the preferred holding time at the stabilizing and relaxing temperature, regardless of how it is achieved, is preferably 300-360 min.
  • the component temperature is preferably reduced to a temperature below 300 ° C. with a defined cooling rate.
  • the cooling rate is preferably 0.5-2 K / min, that is, the cooling is relatively slow, which serves to stabilize and relax the structure.
  • the cooling rate is preferably 1.5 K / min.
  • the respective cooling may take place in a liquid, e.g. in oil, or in air or in an inert gas.
  • the invention further relates to a component of an ⁇ + ⁇ -titanium aluminide alloy, in particular for a piston engine, an aircraft engine or a gas turbine, which is produced in a method of the type described.
  • a component may for example be a blade or a disk of a gas turbine or the like.
