characteristic
VT5 grade belongs to the group of the first domestic titanium alloys for industrial applications. This alloy has a single-phase α-structure. VT5 was developed in the middle of the twentieth century by the design association VIAM. The casting version of VT5L alloy became a domestic analogue of the foreign brand Ti-5Al-22,5Sn. It is not hardened by hardening.

B — high-direction cutting of samples; D — longitudinal; T is tangential, and Π is transverse.
Long-term strength is determined by the amount of force that destroys the sample for a certain time at a specific temperature. That is, as the temperature and load increase, the ultimate strength decreases.
using
High chemical and cryogenic resistance, plasticity, good weldability, insensitivity to incisions, considerable fatigue strength, allows using semi-finished products of the VT series in cryogenic equipment, shipbuilding, machine building, rocket building, aviation, processing industry, etc.
