FIELD: metallurgy.
SUBSTANCE: it can be used for manufacturing of components of gas turbine engines or hypersonic aircrafts, for high-beat components. Powder alloy contains, wt %: aluminium 24-30; cobalt 6-16; niobium 2-4; chrome 2-4; nickel and unavoidable admixtures - the rest. Alloy allows tensile strength at temperature 1100°C not less than 185 MPa, at 1200°C not less than 165 MPa, and creep rupture strength at 1200°C 47-50 MPa. Received material allows high strength at 1100-1200 °C and heat-resistance up to 1400 °C.
EFFECT: obtaining heat-resistant alloys on the basis of alloyed intermetallic semiconductor NiAl.
