FIELD: nonferrous metallurgy.
SUBSTANCE: invention relates to production of refractory nickel alloys based on intermetallide NiAl usable in manufacture of heat-exposed parts of gas-turbine engines. Granulated cast intermetallide NiAl-based alloy contains 20.0-32.0% aluminum, 1.0-2.0% hafnium, 3.0-4.0% chromium, and nickel as base metal.
EFFECT: increased high-temperature strength and heat resistance of alloy, improved reliability of products, and prolonged service time thereof.
