FIELD: metallurgy.
SUBSTANCE: invention relates to cast alloys based on intermetallide Ni3Al, and to products out of these alloys, produced by method of precision casting as per cast models with polycrystal structure, for example, parts of gas turbine engines. Alloy of intermetallide Ni3Al base contains, wt %: Al 8.3-8.9, Cr 4.5-5.2, W 4.0-4.6, Mo 3.8-4.2, Ti 1.2-1.6, Co 5.4-6.0, Zr 0.05-0.50, C 0.15-0.20, La 0.05-0.25, Y 0.01-0.05, Ni - rest.
EFFECT: increased short-term strength and long-term strength of alloy at 1050 and 1100 degrees.
