Conclusions

  1. 1.

    Increasing the degree of deformation in cold and warm rolling increases the texture of α alloy VT5-1.

     
  2. 2.

    With increasing deformation of α+β alloy VT14 the quantity of basal texture, changes, reaching a peak at 70% deformation.

     
  3. 3.

    For α alloy VT5-1, σ b bi b is equal to 1.45, while it is 1.15 for α+β alloy VT14 and 1.13 for β alloy VT15.

     
  4. 4.

    Heating to 1000–1100° in the β region weakens the basal texture of titanium alloys, leading to pyramidal and prismatic orientations. Heating in the α or α+β regions slightly reduces the intensity of the basal texture (by 10–15%). Heating to 880° for quenching leads to a greater reduction of the deformation texture than annealing at 750°.

     
  5. 5.

    The decomposition of the original β phase during aging of alloy VT14 changes the texture of the precipitated α phase to prismatic, which facilitates deformation through the thickness of the plate and lowers the strengthening factor to 0.8.

     
  6. 6.

    Rolling after heating to 800° with small deformation in each pass and changing the direction of deformation by 45° in each pass ensures a larger percentage of the basal texture in alloy VT14 than rolling without changing the direction, with larger deformation in each pass at the same total deformation.
