NICKEL-BASE HEAT-RESISTANT DEFORMABLE ALLOY AND ARTICLE MADE OF THIS ALLOY Russian patent published in 2006 - IPC C22C19/05 

FIELD: metallurgy.

SUBSTANCE: invention relates to nickel-base heat-resistant deformable alloys and articles made of these alloys used in aviation technique, machine engineering and other branches of industry. Invention proposes nickel-base heat-resistant deformable alloy and article made of its. Alloy comprises cobalt, chrome, tungsten, molybdenum, vanadium, aluminum, titanium, niobium, carbon, boron, lanthanum, cerium, magnesium, rhenium and scandium taken in the following ratio of components, wt.-%: cobalt, 14.0-15.9; chrome, 9.7-12.0; tungsten, 1.5-3.5; molybdenum, 3.5-4.5; rhenium, 0.5-2.5; vanadium, 0.4-0.7; aluminum, 3.5-4.2; titanium, 2.5-3.5; niobium, 2.5-4.0; carbon, 0.04-0.10; boron, 0.007-0.014; lanthanum, 0.005-0.015; cerium, 0.003-0.010; magnesium, 0.004-0.015; scandium, 0.003-0.015, and nickel, the balance. Invention provides the development of alloy for turbine disks of gas-turbine engines showing high heat-resistance in the range of temperature 650-850°C, strength and impact viscosity at room temperature, good plasticity in treatment by pressure that provides the high yield of articles and reduces the article price. Invention can be used in making turbine disks of gas-turbine engines and other units and members working at temperatures below 850°C.

EFFECT: improved and valuable technical properties of alloy and articles.
