  1. 1.

    Cast VT20L titanium alloy contaminated during remelting by carbon (up to 0.1–0.3%) possesses significant segregation microinhomogeneity as the result of formation in solidification of TiC-based inclusions of carbide δ-phase, which is the reason for the reduced impact strength.

  2. 2.

    Diffusion annealing of the forgings in the 900–1000°C range for 3–5h leads to dissolution of the δ-phase and provides a high combination of mechanical properties of 0t ≥ 1000 MPa, δ≥10%, anda ≥ 0.3 MJ/m2, the stability of which is preserved after heating to 400°C.
