HEAT-RESISTANT POWDERY ALLOY ON THE BASIS OF NICKEL Russian patent published in 2007 - IPC C22C19/05 C22C1/04 

FIELD: powdery metallurgy; production of the heat-resistant nickel alloys.

SUBSTANCE: the invention is pertaining to the field of the powdery metallurgy; production of the heat-resistant nickel alloys, alloy on the basic, in particular, to production of the heat-resistant nickel alloys nickel intended for production of the heavily loaded details working at the heightened temperatures in the gas-turbine engines (GTE). The heat-resistant powdery alloy on the basis of nickel contains (in mass %): carbon - 0.02-0.10; chromium - 9.0-11.0; cobalt - 14.0-16.0; tungsten - 5.2-6,8; molybdenum - 3.0-3.9; titanium - 3.0-3.9; aluminum 3.2-4.5; niobium - 1.2-2.4; hafnium - 0.05-0.5; boron - 0.005-0.05; zirconium - 0.001-0.05; magnesium - 0.001-0.05; manganese -0.001-0.5; silicon -0.001-0.5; iron - 0.001-1.0; nickel - the rest. The technical result of the invention is the increased plasticity, the improved high-temperature creeping characteristics and the reduction of the speed of propagation of the fatigue crack.

EFFECT: the invention ensures the increased plasticity, the improved high-temperature creeping characteristics, the reduced speed of propagation of the fatigue crack.
