Definitions
- the invention relates to a nickel-based SX alloy with improved TMF properties, a raw material and a component.
- the LCF service life at high strain ranges is also reduced by the brittle fracture behavior between room temperature and 923 K.
- a material having the following composition is advantageous:
- Co Co 9.0% - 11%, especially 10%
- Rhenium (Re) 1.0% - 1.30%, in particular 1.25%
- Yttrium (Y) 0.017% - 0.023%, especially 0, 02%.
- This material differs from previous Ni-SX compositions by a significantly higher proportion of chromium (Cr), a reduced proportion of rhenium (Re), the addition of silicon (Si) and yttrium (Y) and the fact that it is not titanium ( Ti), except for impurities of max. 0.1 wt. -%.
- Silicon (Si) improves oxidation resistance
- Si silicon
- the LCF life is increased by the increased yield strength at low temperatures and high strain ranges. Reducing the proportion of rhenium (Re) reduces the risk of TCP phase formation, which has a very negative effect on TMF behavior, provided that it is formed during operation.
- the reduction of rhenium (Re) also allows an increase in the chromium content without stabilizing unwanted TCP phases.
- the new material should have oxidation properties at least at the level of Alloy 247.
- the addition of yttrium (Y) has the effect that the material has a particularly good cyclic oxidation properties (improvement of the A1203 topcoat adhesion).
- the silicon (Si) is mainly incorporated in the ⁇ ⁇ phase, while it is incorporated in titanium-containing materials in the ⁇ phase.
- the accumulation of silicon (Si) in ⁇ -phase is rather undesirable because this would favor the precipitation of sputtering phases in the channels (eg G-phase).
- the shear strength is increased by the silicon incorporation into the ⁇ ⁇ phase.
