Definitions
- the invention relates to an austenite alloy, a blank which is produced in particular by forging and is suitable for components in high-temperature applications, and a method.
- forged disks for rotors of turbines in particular of gas turbines, have hitherto been produced from different forged steels.
- NiCrMoV is used for compressor disks or CrMoWVNbN for turbine disks.
- the A286 standard alloy has long been evaluated for use in steam turbine blades. It was shown that the material A286 standard itself has a potential for use up to 923K.
- Annealing annealing [AN] and various aging as heat treatments (aging [AG]) for austenite in general and specifically for the subject of the alloy according to the invention:
- the first solution annealing is at 1253K, the first aging at 1033K and the second aging at 993K;
- the first solution annealing is at 1253K, the first aging at 993K and the second aging at 1033K and the third aging at 953KC,
- the first solution annealing is at 1253K, the first aging at 1033K, the second aging at 993K and the third aging at 953K,
- the first solution anneal is at 1293K, the first aging at 1033K and the second aging at 923K.
- Austenitic steel has the following composition:
- a blank is cast from such an alloy according to the prior art and forged according to the prior art.
