FIELD: metallurgy.
SUBSTANCE: invention relates to production of Ni2Al intermetallide-based alloys and articles made thereof in controlled crystallisation that feature columnar structure, for example, gas turbine blades operates at temperatures approximating to 1200°C. Proposed alloy features higher short-term strength at 20-1200°C and long-term strength at 1000-1200°C. Proposed alloy contains the following components in wt %: aluminium - 8.0-8.8, chromium - 3.0-4.0, molybdenum - 4.0-5.0, tungsten - 2.0-3.0, carbon - 0.002-0.05, cobalt - 4.0-6.0, rhenium - 0.15-0.65, lanthanum - 0.005-0.25, tantalum - 5.6-6.4, cerium - 0.001-0.02, nickel making the rest.
EFFECT: higher reliability, longer life.
