VT6, Grade 5, 6al-4v

characteristic

Titanium series BT, grades 6 and 6C belongs to the group of α + β-alloys. The production is standardized by GOST 19807−74, and also OST 90013−81. The alloy VT6 contains 4.5% vanadium and 6% Al, and the alloy BT6C 4% vanadium and 5% Al. Aluminum hardens the α + β phase, and vanadium stabilizes the β-phase and inhibits the formation of α-2 superstructure in the α phase. Heat treatment of the alloy increases the strength to 20% without loss of ductility. The casting variant of the alloy is designated by the letter A: BT6L.

Heat treatment

Annealing increases the β-phase content to 10%. Aluminum hardens the α + β phase. Heat treatment of the alloy increases the strength to 20% without loss of ductility. High plasticity allows the use of cold deformation during the molding of semi-finished products. Alloy BT6kt with a reduced content of impurities is used at t ° to -196 ° C.
