Definitions
- the present invention relates to a method for producing forged components from a TiAl alloy, in particular components for gas turbines, preferably aircraft turbines and in particular turbine blades for low-pressure turbines. Moreover, the present invention relates to corresponding components.
- titanium aluminides Due to their low specific weight and their mechanical properties, components of titanium aluminides are of interest for use in gas turbines, in particular aircraft turbines. However, in the case of titanium aluminide materials, the microstructures must be precisely adjusted in order to achieve the desired mechanical properties.
- the components are subjected to a two-stage heat treatment after forging, wherein the first stage of the heat treatment provides recrystallization annealing below the ⁇ / ⁇ transformation temperature for a period of 50 to 100 minutes.
- the annealing at a temperature below the ⁇ / ⁇ transformation temperature at which ⁇ -titanium is converted into ⁇ -TiAl in accordance with the phase diagram for the TiAl alloy used may take place as close as possible to the ⁇ / ⁇ transformation temperature, with a temperature of 15 ° C, in particular 10 ° C, below the ⁇ / ⁇ - conversion temperature should not fall below.
- the recrystallization annealing may preferably be carried out for 60 to 90 minutes, especially 70 to 80 minutes.

- the cooling in the recrystallization annealing can be carried out by air cooling, wherein in the temperature range between 1300 ° C and 900 ° C, the cooling rate> 3 ° C per second should be to set a fine lamellar structure of a 2 -Ti 3 AI and ⁇ -TiAl in the corresponding a 2 - and ⁇ -phase, which ensures the required mechanical properties.
- the cooling in the second heat treatment stage, so the stabilization annealing, can be done with correspondingly lower cooling rates in the oven.
- the heat treatment steps are carried out as accurately as possible at the corresponding selected temperature.
- an increasingly precise adjustment of the temperature and holding the components at the appropriate temperatures associated with increasing effort so that a compromise must be found for an economically meaningful processing.
- a temperature adjustment with a deviation in the range of 5 ° C to 10 ° C up and down from the target temperature has been found to be advantageous.
- the selected SolN temperature for the heat treatment steps of the present invention can be set and maintained in a corresponding temperature window of 5 ° C to 10 ° C deviation from the target temperature up and down.

- Such alloys are also referred to as TNM alloys.
- an alloy of 42 to 45 atomic percent aluminum, 3 to 5 atomic percent niobium, and 0.5 to 1.5 atomic percent molybdenum may be used.
- the aluminum content may be selected in the range of 42.8 to 44.2 atomic percent aluminum, while 3.7 to 4.3 atomic percent of niobium and 0.8 to 1.2 atomic percent of molybdenum may be alloyed.
- the alloy may be alloyed with boron in the range of 0.05 to 0.15 atomic percent boron, more preferably 0.07 to 0.13 atomic percent boron.
- the alloy may contain unavoidable impurities or other constituents such as carbon, oxygen, nitrogen, hydrogen, chromium, silicon, iron, copper, nickel and yttrium, the content of which being ⁇ 0.05% by weight of chromium, ⁇ 0.05% by weight of silicon, ⁇ 0.08 weight percent oxygen, ⁇ 0.02 weight percent carbon, ⁇ 0.015 weight percent nitrogen, ⁇ 0.005 weight percent hydrogen, ⁇ 0.06 weight percent iron, ⁇ 0.15 weight percent copper, ⁇ 0.02 weight percent nickel and ⁇ 0.001 weight percent yttrium , Further constituents may be contained individually in the range of 0 to 0.05 percent by weight or in total from 0 to 0.2 percent by weight.
- the forging of the corresponding components can be carried out by drop forging in the ⁇ - ⁇ - ⁇ temperature range, wherein as a raw material for forging cast and / or hot isostatically pressed blanks can be used.
- the blanks themselves can be produced by melting in vacuum or inert gas withsverzehreri- the electrodes or in the cooled crucible by plasma arc melting, wherein a single or multiple remelting of the alloy can be performed.
- Remelting may be by vacuum induction melting or vacuum arc remelting (VIM vacuum induction melting) and the poured material may be hot isostatically pressed, with temperatures> 200 ° C at a pressure> 190 MPa and a holding time> 4 hours can be applied.
