Abstract In this paper, Ti-5Al-3Mo-3Cr-1Zr-0.1Si alloy was deformed in two-phase zone and annealed in single-phase zone to study the effects of deformation temperature, degree of deformation, and deformation-annealing articulation on the static recrystallisation behaviour of the alloy, and established a model for the correlation between the deformation temperature and the β grain size after annealing. The results show that the low deformation temperature is conducive to the β grain refinement. This is attributed to the increase of α phase content at low deformation temperature, which in turn increases the deformation distortion energy of β matrix and promotes the recrystallized nucleation of β phase. The average grain size of the alloy after annealing decreases with the increase of deformation degree. When the deformation degree exceeds 40%, the β grain average size gradually tends to stabilize, about 136 μm. The cooling rate after the deformation also affects the grain size after annealing, and the faster the cooling rate is, the larger the β grain size is. When the alloy is heated directly to the single-phase zone for annealing without cooling after pre-deformation, the β grains are uniformly refined.

Key words： titanium alloy deformation heat treatment recrystallization β grain uniform refinement; grain size model
