Abstract (en)
[origin: WO2022200175A1] A nickel-based alloy composition is specified, comprising nickel as main constituent and the following further constituents in weight per cent (wt%): 0.04 to 0.10% carbon (C), 8 to 13% tantalum (Ta), 12 to 20% chromium (Cr), 3 to 25% cobalt (Co), less than 0.03% manganese (Mn), less than 0.06% silicon (Si), 0 to 6% molybdenum (Mo), less than 5.0% iron (Fe), 2 to 4% aluminium (Al), less than 0.01% magnesium (Mg), less than 0.02% vanadium (V), 0 to 6% tungsten (W), less than 1% titanium (Ti), less than 0.03% yttrium (Y), 0.005 to 0.015% boron (B), less than 0.003% sulfur (S), 0.005 to 0.04% zirconium (Zr) and less than 3% hafnium. Also specified are the use thereof for an additive manufacturing method, a method for additive manufacturing of a component from a powder of said alloy composition, a corresponding intermediate alloy, and a component consisting of the nickel-based superalloy.
