HEAT-RESISTANT WELDED NICKEL-BASED ALLOY AND A PRODUCT MADE OF IT Russian patent published in 2022 - IPC C22C19/05 F01D5/28 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, namely to heat-resistant deformable nickel-based alloys, and can be used for the manufacture of parts and components of gas turbine engines, power plants, power machines operating for a long time at temperatures from 600 to 800°C and up to a temperature of 900°C. Heat-resistant welded nickel-based alloy contains, wt. %: carbon 0.005-0.10, chromium 13.0-19.0, cobalt 10.0-21.0, molybdenum 2.0-6.5, tungsten 0.7-3.0, niobium 3.6-4.65, aluminum 1.9-2.6, titanium 0.4-1.15, zirconium 0.11-0.25, boron 0.0001-0.008, lanthanum 0.0001-0.08, magnesium no more than 0.06, iron no more than 2.0, at least one component selected from tantalum, vanadium and hafnium: tantalum 0.1-3.0, vanadium no more than 0.8, hafnium no more than 0.1, nickel and unavoidable impurities being the rest.

EFFECT: high values of long-term strength of the alloy at a temperature of 700°C, short-term strength at room and elevated temperatures with structural stability at a temperature of 800 to 900°C are provided; possibility of cold deformation of the alloy and weldability by argon arc welding is also provided.
