FIELD: metallurgy.
SUBSTANCE: production of the sheet with fine-grained structure of α/β-titanium alloy comprises forging of the titanium alloy slab to get the sheet blank to be heated to the temperature higher than that of conversion into beta-phase by the magnitude from approx 100°F (37.8°C) to approx 250°F (121°C) and further heating. Than, it is heated to the temperature from approx 1400°F (760°C) to approx 1550°F (843°C) with further hot rolling to get the blank of intermediate depth. Than, it is heated to the temperature from approx 1400°F (760°C) to approx 1550°F (843°C) with further hot rolling to get the blank of final depth. Now, annealing, grinding and etching are performed.
EFFECT: sheet blank with fine-grained structure suitable for low-temperature forming.
