General characteristics

Titanium grades are classified according to crystal lattice configuration: cubic (β-state), in a form of hexahedron (α-state), mixed (α + β). Titanium gost VT9 refers to a group of α + β alloys. It is alloyed with aluminium — 6.4%, molybdenum — 3%, zinc — 1.5%, silicon — 0.25%. It is invented in 1960 by VIAM. This alloy is a first thermally hardened alloy that has been utilized in industry. The highest strength properties are achieved at temperature of up to 500 ° C.

Chemical composition of alloy according to GOST 19 807- 91

Al N H Ti Si C Fe Zr O Mo
5.8 -7.5 ≤0.05 ≤0.015 86.15−89.9 0.2 — 0.35 ≤0.1 ≤0.25 1−2 ≤0,15 2−3

Note: titanium is a basis; its percentage is noted in a table. Impurities are permissible to 0.3%.

Volume weight Properties t° of melting Application Manufacturing process
4,48 g/cm³ A high percentage of aluminium and silicon doping increases a strength, heat resistance in comparison to titanium grade 5. It is intended to work at temperature of 400 — 500 °C. Combination of qualities ensures isothermal and double annealing. Content of β — phase in annealed alloy is 10%. Alloys are hardened by age-hardening and thermohardening. 980−1020° Gas-turbine engines: blades and discs, parts of compressors etc. It is satisfactorily deformed in a hot condition. During cold pressure treatment, workability is worse in comparison to titanium grade 5. Welding is not recommended.


Rod, sheet, wire, tube made of this titanium grade are widely used in aircraft, petrochemical engine industry for manufacture of compressors details, pumps, pipelines, parts of gas turbine engines that operate at a temperature of 400 — 500 °C.
