HEAT-RESISTANT NICKEL ALLOY FOR DISKS OF GAS TURBINE ENGINES Russian patent published in 2024 - IPC C22C19/05 

FIELD: metallurgy.

SUBSTANCE: invention relates to heat-resistant nickel alloys intended for the manufacture of high-loaded rotor parts, in particular disks of gas turbine engines, operating under conditions of active action of static and dynamic loads at temperatures up to 800–850 °C. Heat-resistant nickel alloy contains, wt.%: carbon 0.05–0.1, chromium 6.0–10.0, cobalt 16.0–20.0, tungsten 4.0–7.0, molybdenum 3.0–5.0, titanium 3.0–5.0, aluminum 3.0–5.0, niobium 2.0–3.5, tantalum 3.0–6.0, hafnium 0.05–0.5, vanadium 0.5–1.5, manganese 0.05–0.3, boron 0.005–0.05, zirconium 0.001–0.05, scandium 0.01–0.1, magnesium 0.001–0.05, cerium 0.01–0.05, lanthanum 0.01–0.05, yttrium 0.01–0.05, nickel—the rest.

EFFECT: alloy is characterized by high resistance to deformation.
