FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly to heat-resistant nickel alloys. It can be used in gas turbine engine for manufacturing of heavy duty components, operating at increased temperatures. Heat-resistant sintered nickel alloy, contains, wt %: carbon 0.07-0.12; chrome 10.0-12.0; cobalt 13.0-15.0; tungsten 4.6-5.6; molybdenum 2.7-3.5; titanium 2.5-3.5; aluminium 3.7-4.4; niobium 3.1- 3.8; hafnium 0.05-0.2; boron 0.005-0.05; zirconium 0.001-0.05; magnesium 0.001-0.05; cerium 0.001-0.05; iron 0.01-1.0; manganese 0.001-0.5; silicon 0.001-0.5; nickel - the rest.
EFFECT: obtaining allot, which allows high strength, high-temperature strength, resistance to "MTsU" at reduction of rate of fatigue crack propagation at operating temperatures.
