摘要

In this paper, we analyze effects of hot rolling on the shape, structure, texture, and properties of a Ti–4.5Al–3Mo–V alloy (VT14) titanium alloy. The phase composition, texture, and morphology of the formed phases in the initial state and after rolling are determined. The effect of the deformation degree between the passes on the formation of various components of the deformation texture and recrystallization is shown. The dependence of VT14 alloy widening during flattening under the action of hot deformation in one pass are analyzed. A decrease in the widening coefficient at a similar degree of deformation is noted. Relationships between the studied hot deformation routes, the α/β-phase ratio, the morphology of the secondary α phase, the development of recrystallization in the β phase, as well as the hardness and contact elasticity modulus of VT14 alloy were determined.
