The invention relates to a method for the generative production of a component (3), in particular of a turbo-engine component, wherein material (4) is bonded layer-wise selectively to a layer or to a substrate (6) disposed therebeneath, wherein before, during and/or after the bonding a laser (1A; 1B; 2) additionally acts on the material (4).
摘要:
The invention relates to a method for producing forged components made of a TiAl alloy, in particular turbine blades. The components are forged and undergo a two-stage heat treatment after the forging process. The first stage of the heat treatment comprises a recrystallization annealing process for 50 to 100 minutes at a temperature below the γ/α transition temperature, and the second stage of the heat treatment comprises a stabilization annealing process in the temperature range of between 800 °C to 950 °C for 5 to 7 hrs. The cooling rate during the first heat treatment stage is greater than or equal to 3 °C/sec, in the temperature range between 1300 °C to 900 °C.
