FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy, namely to production of heat-resistant powder alloys based on NiAl intermetallic compound, and can be applied in aviation, space and power industries for manufacturing of heat-loaded parts operating under high temperature conditions relatively low mechanical stress. Granulated alloy based on NiAl intermetallic compound contains, wt %: aluminium 24.5-29.9; cobalt 5.27-6.35; chrome 5.98-7.3; hafnium 1.0-1.2; boron 0.03-0.04; the rest is nickel.
EFFECT: high heat strength and plasticity of alloy.
