FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to heat-resistant intermetallic nickel-based alloys intended for production by precise casting methods of gas turbine engines. Nickel intermetallide-based alloy contains, wt. %: 8.1–8.6 Al, 5.6–6.3 Cr 4.5–5.5 Mo, 2.5–3.5 W, 0.3–1.0 Ti, 0.15–0.2 C, 4.0-5.0 Co, 1.2–1.6 Re, 0.002–0.2 La, 0.05–1.0 Zr, 0.002–0.2 Nd, 0.002–0.2 Y, Ni – rest.
EFFECT: alloy is characterized by low content of oxygen in alloy, high values of short-term and long-term strength at temperatures of 1,100–1,200 °C.
