FIELD: metallurgy. ^ SUBSTANCE: invention relates to non-ferrous metallurgy, particularly to creation of titanium alloys, provided for usage in the capacity of constructional material for manufacturing of shell, longerons, frames, fuselage, wings, aggregates and other details of aircraft. Alloy on the basis of titanium contains, wt %: aluminium 5.3-6.8, vanadium 3.5-5.3, iron 0.02-0.6, zirconium 0.001-0.3, carbon 0.005-0.1, silicon 0.01-0.15, manganese 0.001-0.15, copper 0.001-0.095, chrome 0.001-0.095, oxygen 0.02-0.2, nitrogen 0.005-0.05, hydrogen 0.003-0.015, titanium - the rest. ^ EFFECT: receiving of ally with high strength properties at biaxial tension, reduced notch sensitivity and reduced density, providing of reliability increasing of products operation. ^ 2 cl, 2 tbl, 1 ex |
