Characteristics of the alloy
Titanium alloys BT6, BT6S belong to α+β-alloys. Titanium is produced according to GOST 19 807−74 and OST 90 013−81. VT6 is alloyed with 6% Al and 4.5% V, whereas BT6C is alloyed with 5% Al and 4% V. Aluminum hardens α+β phase, and vanadium stabilizes β-phase and hinders the formation of alpha-2 superstructure in α-phase. The annealed state contains 10% of the β-phase. Quenching and aging increase the strength by about 15 — 20% while maintaining a fairly high ductility. Casting variant of VT6L.

Applications
BT6 alloy is used in annealed and heat hardened condition. The annealed alloy contains about 10% β-phase. It is highly technical in pressure processing, a variant with a reduced percentage of impurities (BT6kt) is used at cryogenic temperatures down to -196 ° C.
