FIELD: metallurgy.
SUBSTANCE: invention concerns metallurgy field. Particularly it concerns castable alloy on the basis of intermetallic compound Ni3Al and products, received by means of investment casting method with directed columnar and monocrystalline structures, such as buckets and nozzle blades, nozzle blades blocks and other details of gas turbine engines for aircraft, automotive industry. For increasing of high-temperature strength of alloy in the range of temperatures 900-1100°C on the basis of 500 hours and increasing of ingot yield at moulding of details with monocrystalline structure from alloy it contains, wt %: Al 8.0-9.0, Cr 4.5-5.5, W 1.8-2.5, Mo 4.5-5.5, Ti 0.6-1.2, C 0.01-0.08, Co 3.5-4.5, La 0.0015-0.015, Sc 0.015-0.03, Ni - the rest.
EFFECT: increasing of high-temperature strength and product yield.
