DEFORMABLE NICKEL-BASED HEAT-RESISTANT ALLOY Russian patent published in 2019 - IPC C22C19/05 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular to nickel-based heat-resistant alloys, and can be used for production of turbine wheels of gas turbine engines and plants designed for operation under conditions of active action of high thermal stresses, temperatures, static and variable loads. Deformable heat-resistant nickel-based alloy contains, wt%: carbon 0.03–0.12, chromium 7.0–10.0, cobalt 16.0–28.0, tungsten 2.5–6.0, molybdenum 2.8–4.8, titanium 2.5–5.4, aluminum 3.2–4.6, niobium 0.5–3.0, tantalum 2.6–4.6, hafnium 0.05–0.2, rhenium 1.0–3.0, boron 0.005–0.015, zirconium 0.005–0.03, cerium 0.01–0.05, lanthanum 0.01–0.05, yttrium 0.01–0.05, magnesium 0.01–0.06, nickel – the rest.

EFFECT: alloy is characterized by high values of long-term, short-term strength and plasticity in temperature range from 20 to 850 °C.
