Definitions

  • the invention relates to a nickel-based SX alloy with improved TMF properties, a raw material and a component.
  • SX materials based on nickel are currently being investigated. These materials are said to have a significantly higher creep resistance in comparison to the known SX materials and in particular at high levels of creep resistance
  • 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% -1.25%, especially 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% by weight.
  • Silicon (Si) improves oxidation resistance
  • 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.
  • Y yttrium
  • the silicon (Si) is mainly incorporated in the ⁇ ⁇ phase while being 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.
