FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy of alloys, namely, high-entropy alloys that can be used for the production of structural elements and parts operating at high temperatures in aircraft and rocket engines, and can also be used for the manufacture of nozzle (guide) blades of gas turbine plants, operating in aggressive environments at temperatures of 700-1100°C. High-entropy heat-resistant alloy contains, at.%: zirconium 5.50, aluminum 8.27, niobium 25.5, titanium 25.2, vanadium 25.5, silicon 5.0, chromium 5.0, calcium and REM 0.03 .
EFFECT: alloy is characterized by low density and increased strength characteristics at elevated temperatures and exposure to alternating loads.
