FIELD: metallurgy.
SUBSTANCE: invention can be used to produce elements and parts of structures operating under high temperatures in aircraft and rocket engines. Alloy AlNbTiVZrx, where x takes values from 0.1 to 0.25, has the following component ratio, at.%: 24-24.6 of titanium, 22.4-23.6 of niobium, 21.9-22.8 of vanadium, 3.3-6.7 of zirconium, the rest is aluminium. The invention is aimed at obtaining the alloy with specific yield strength of 166-174⋅ kPaM3/Kg at T = 800°C, low density less than 6 g/cm3, and plasticity at room temperature of not less than 3%.
EFFECT: increasing the yield point, reducing the density and increasing the plasticity.
