NICKEL-BASED ALLOY WITH SILICON, ALUMINUM, AND CHROMIUM

摘要

A nickel-based alloy, consisting of (in mass %) 1.5-3.0% Si, 1.5-3.0% Al, and >0.1-3.0% Cr, where Al+Si+Cr is ≧4.0 and ≦8.0 for the contents of Si, Al, and Cr in %; 0.005-0.20% Fe, 0.01-0.20% Y, and <0.001-0.20% of one or more the elements Hf, Zr, La, Ce, Ti, where Y+0.5*Hf+Zr+1.8*Ti 0.6*(La+Ce) is ≧0.02 and ≦0.30 for the contents of Y, Hf, Zr, La, Ce, and Ti in %; 0.001-0.10% C; 0.0005-0.10% N; 0.001-0.20% Mn; 0.0001-0.08% Mg; 0.0001-0.010% O; max. 0.015% S; max. 0.80% Cu; Ni remainder; and the usual production-related impurities.
