General characteristics
Alloy VT5 is one of the first domestic industrial titanium alloys. It was developed by VIAM in 1950-ies. Foundry option ВТ5Л. VT5−1 have been proposed VIAM in 1958 and has become the equivalent of foreign brands Ti-5Al-22,5 Sn. This alloy has a single phase α-structure. It does not harden with heat treatment.

Heat resistance
Highest voltage — creep strength, under whose influence the material is deformed by a given amount at a given temperature.
Long-term strength
Is the maximum voltage that Deplete the material after a certain time at a given temperature. Thus, at an elevated temperature with an increase in the duration of the load decreases the tensile strength.
