FIELD: metallurgy.
SUBSTANCE: nickel-based superalloy is proposed with a strengthening gamma-line-phase, containing the following components: up to 20 wt% Co, from 12 to 14 wt % Cr, from 1 to 2 wt % Mo, from 1.4 to 2.8 wt % W, from 5.1 to 5.9 wt % Al, from 1.1 to 1.6 wt % Ti, from 3 to 7 wt % Ta, from 0.01 to 0.3 wt % C+Zr+B, from 0.05 to 1 wt % Hf, from 0.05 to 1 wt % Si, and from 0.01 to 0.2 wt % of rare earth elements. Also alloy application as a hot machine component is proposed.
EFFECT: alloy is characterised with high resistance to high-temperature corrosion, oxidation, high compatibility with coatings, phase stability, high resistance to creepage and low density.
