Nickel-based superalloy for industrial turbine blades.

摘要

Nickel-based superalloy suitable for directed solidification especially of industrial gas turbine components, characterised in that its weight composition is the following: Co : 0 to 5% Cr : 13 to 16% W : 0 to 2% Mo : 2 to 3.5% Al : 3.5 to 4% Ti : 3.5% Ta : 3.5 to 4% Hf : 0 to 1% C : 0 to 600 ppm Zr : 0 to 150 ppm B : 0 to 150 ppm Ni : remainder to 100%
