Commonly used methods of annealing titanium sheet, solution and aging treatment. Annealing is to eliminate stress, improve plasticity and organizational stability, in order to obtain a better overall performance. Typically α alloys and (α + β) alloy annealing temperature selected in the (α + β) ─ → β phase transition point below 120 ~ 200 ℃; solution and aging treatment is rapid cooling from high temperature zone to obtain martensite α 'phase and the metastable β phase, and then incubated in the temperature region of these metastable phase decomposition to obtain compound α phase or the dispersed second phase particles, achieve the purpose of strengthening the alloy. Typically (α + β) quenching the alloy in (α + β) ─ → β phase transition point of 40 ~ 100 ℃ were metastable β quenched alloy in the (α + β) ─ → β phase transition point above 40 ~ 80 ℃ get on. Aging treatment temperature is generally 450 ~ 550 ℃.
