FIELD: powdery metallurgy, alloys.
SUBSTANCE: invention relates to compositions of nickel-base powdery heat-resistant alloys. Proposed alloy comprises the following components, wt.-%: carbon, 0.02-0.08; chrome, 8.0-10.0; cobalt, 1.0-6.0; tungsten, 5.2-6.0; molybdenum, 3.4-4.2; titanium, 2.3-2.9; aluminum, 4.6-5.3; niobium, 1.0-1.9; hafnium, 0.5-0.4; boron, 0.005-0.05; zirconium, 0.001-0.05; magnesium, 0.001-0.05; manganese, 0.001-0.05; silicon, 0.001-0.5; iron, 0.001-0.5, and nickel, the balance. The proposed alloy shows high creep and plasticity indices, fatigue crack spreading low spreading value that enhances working resource of articles made of the proposed alloy.
EFFECT: improved and valuable technical properties of alloy.
