Abstract (en)
[origin: WO2006053826A2] The invention relates to a nickel-based superalloy. The inventive alloy is characterised by the following chemical composition (amount in wt. %): 7.7-8.3 Cr, 5.0-5.25 Co, 2.0-2.1 Mo, 7.8-8.3 W, 5.8-6.1 Ta, 4.9-5.1 AI, 1.3-1.4 Ti, 0.11 -0.15 Si, 0.11 -0.15 Hf, 200-750 ppm C, 50-400 ppm B, 0.1 -5 ppmS, 5-100 ppm Y and/or 5-100 ppm La, and the remainder is Ni and impurities arising from the production thereof. Said nickel-based superalloy is characterised in that it is very pourable, is highly resistant to oxidation and has a good compatibility to the TBC layers applied to the surface thereof.
