Nickel-Basis-Superlegierung

摘要

A nickel-base superalloy, in particular for the production of large single-crystal components, consisting essentially of 6.0-6.8 % Cr, 8.0-10.0 % Co, 0.5-0.7 % Mo, 6.2-6.6 % W, 2.7-3.2 % Re, 5.4-5.8 % Al, 0.6-1.2 % Ti, 6.3-7.0 % Ta, 0.15-0.3 % Hf and 0.02-0.04 % C (all by weight), 40-100 ppm B and 15-50 ppm Mg, the remainder being made up of nickel and impurities.
