FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to high-entropy alloys of the system Al-Cr-Nb-Ti-V-Zr, which can be used as structural materials. Disclosed is a high-entropy alloy of the system Al-Cr-Nb-Ti-V-Zr, obtained by vacuum-arc remelting and containing chemical elements at the following percentage ratio, at.%: aluminium 1, chrome 9, niobium 35, titanium 5, vanadium 40 and zirconium 10.
EFFECT: alloy has high mechanical properties: yield strength 1090 MPa, ultimate strength of 1456 MPa and compression ductility of 14.7% at room temperature, and yield strength of 920 MPa, ultimate strength of 1192 MPa and ductility >50% at temperature of 800 °C.
