Title:

TITANIUM ALLOY AND METHOD FOR HEAT TREATMENT OF LARGE-SIZED SEMIFINISHED MATERIALS OF SAID ALLOY

Document Type and Number:

WIPO Patent Application WO/2002/006544

Kind Code:

A1

Abstract:

The inventive titanium alloy comprises, expressed in mass %: aluminium 4.0-6.0; vanadium 4.5-5.0; molybdenum 4.5-5.0; chromium 2.0-3.6; ferrum 0.2-0.5; the rest being titanium. An equivalent molybdenum content is determined as corresponding to Mo ¿equiv.?$m(G) 13.8. The total aluminium and zirconium content does not exceed 7.2. The inventive method for heat treatment consists in heating to t¿$g(b)<>$g(a)+$g(b)?-(30-70) °C, conditioning during 2-5 hrs. at that temperature, air or water cooling and age-hardening at a temperature ranging from 540 °C to 600 °C during 8-16 hrs. Said alloy has a high volumetric deformability and is used for manufacturing massive large-sized forged and pressed pieces having a high strength level, satisfactory characteristics of plasticity and fracture toughness.
