FIELD: metallurgy.
SUBSTANCE: invention can be used for heavy duty parts - disks and shafts operating at raised temperature in gas turbine engines. Here is claimed powder heat resistant alloy containing wt %: carbon - 0.06-0.14, chromium - 10.0-12.0, cobalt - 4.0-6.0, tungsten - 1.0-2.0, molybdenum - 5.0-5.6, titanium - 3.0-3.6, aluminium - 4.5-5.5, niobium - 2.5-3.2, boron - 0.005-0.05, zirconium - 0.001-0.05, magnesium - 0.001-0.05, cerium - 0.001-0.05, lanthanum - 0.005-0.05, nickel - the rest. Also, ratio of summary contents of tungsten and molybdenum to summary contents of aluminium and titanium is 0.66-1.01.
EFFECT: raised heat resistance, increased resource of engine operation at higher working temperatures.
