Definitions

  • the invention relates to a method for producing a forgings for turbine blades made of a gamma titanium-aluminum base alloy
  • Titanium alloy of 6 at.% Or 8 at.% And (alpha + beta) or near alpha structure are known from US Pat EP 1 127 953 known and are used for a production of poppet valves. This involves upsetting a rod material above the beta conversion and finish-forging the valve disc with an alpha structure in a heat.
  • Titanium-aluminum base alloys are essentially formed of titanium aluminide intermetallics and have a high melting point, low density, a high specific modulus of elasticity, good oxidation behavior and high specific tensile strength and creep resistance in the temperature range of 600 ° C to 800 ° C, So meet the ever-increasing demands on special materials such as for next-generation components of aircraft engines and internal combustion engines.
  • Titanium aluminide materials are not yet optimized with regard to their alloy composition and their production and processing.
  • An alloy that has good processability as well as balanced mechanical properties that can be created by suitable heat treatments includes the elements titanium, aluminum, niobium, molybdenum and boron and is therefore referred to in the art as TNM alloy.
  • the object of the invention is to improve the difficult and expensive processing of titanium aluminide materials and has the task of creating a method of the type mentioned above for economic production.
  • This object is achieved in a method for producing a forging, in particular a turbine blade, from a gamma-titanium-aluminum base alloy, in which a cylindrical or rod-shaped starting or starting material in one or more steps at those points at which the forging to be formed or the turbine blade to be formed has a volume concentration, heated by electric current passage or by induction over the cross section to a temperature higher 1150 ° C and deformed by application of force, in particular upsetting deformed and such a forging blank is created with different cross-sectional areas over its longitudinal extent, which blank in one or more subsequent steps is final deformed, wherein the or the subsequent step (s) for the final deformation of the forging blank each of an at least partially coating the surface with a heat radiation and thereby the devisflä is formed from heating the forging blank to forming temperature, from a heat soak and from a reshaping of the same, in particular in a die, is formed.
  • the alloy consists mainly of gamma-titanium-aluminum and alpha 2-titanium-aluminum and has only a possibly small proportion of beta-phase, which phase has ductile properties depending on the temperature.
  • beta-phase increases in the material, which justifies an improvement in the ductility of the material.
  • upsetting may be done at several points in the sequence.
  • a forged blank produced according to the invention can now be finally deformed, with advantage being due to the volume concentrations, a Gesenk spallung with less material flow and / or material use can take place.
  • a transport of forging blank or intermediate product from the heating furnace to the deformation plant with the tool or with a die, esp. can cause a critical cooling of the surface portion of the deformed part, in an embodiment of the invention, a method in which or the sequential step (s) of final deformation of the forging blank or intermediate product for turbine blade production from at least partially coating the surface with a heat radiation and thereby the superficial one Temperature decrease-reducing agent, a heating of the forging blank or intermediate product to forming temperature, a heat soak, a transfer and a forming thereof, esp.
  • a die is formed (be), advantageously feasible.
  • the oxide phase acts as a heat-resistant insulating component, with one or more additive (s) or adhesives having smaller proportions connecting (bonding) and retaining (holding) the oxide grains.
  • the liquid component (s) serve to homogenize the phases and to adjust a desired level of liquid for homogeneous application to the surface of the workpiece or part.
  • a method which can be carried out without error is advantageous in which the final deformation takes place in a die which has a temperature which is at least 300 ° C. lower than the forging blank or the intermediate product.
  • a method according to the invention in which the final deformation takes place in a die having up to 900 ° C, preferably up to 800 ° C, lower temperature than the forging blank or the intermediate intensifies the above advantages, because such a low mold temperature Use of commonly used hot working steels for thermally tempered dies allows for no danger the hard waste of the same must be feared in the operation.
  • the method of manufacturing turbine blades e.g. made of a TNM alloy, usable.
  • a power source (not shown) is connected to a terminal 2 and a slightly concave shaped flat caliper 3.
  • a rod 1 is pressed in a press on the flat saddle 3, wherein between the flat saddle 3 and the terminal 2 electric current flows, which heats the rod in this area by the ohmic resistance.
  • a heating of a rod or rod part can also be done by means of an induction coil and alternating current.
  • titanium-aluminum base alloys have particularly good compression properties and are not prone to buckling. Furthermore, a rapid, targeted heating of a rod area is possible by a heat technology with electrical current passage or by induction, with a precise adjustment of the forming temperature in the so-called. Deformability window of the alloy can be achieved.
  • FIG. 3 and FIG. 4 show a puncture of one end of a rod 1 in a mold 3 to form a desired shaped end portion 11th
  • Blanks, as in FIG. 3 and FIG. 4 2, for a turbine blade forging, a rod having a diameter of 30mm ⁇ and a length of 225mm was made of an alloy Ti-43.5Al- (Nb-Mo-B) 5 at%.
  • the production length was 192mm with a head diameter of 45mm and a head length of 63mm.
  • the heating and compression time was 60 sec., With a heating current of 7740 A and a forming temperature of 1250 ° C had been set.
  • Fig. 5 shows in a form compressed blanks.
