FIELD: metallurgy, in particular feed from titanium-based alloy for aircraft industry and engineering. ^ SUBSTANCE: claimed method includes feed heating, deformation thereof in die, heated to temperature of total titanium-based alloy polymorphous conversion or above: isothermal holding at die temperature for time effective to total titanium-based alloy recrystallization; and quench. Feed is heated up to temperature by 10-30oC lower than the same of total polymorphous conversion; deformation is carried out in two steps: in the first one deformation rate is sufficient to feed heating up to die temperature, and deformation degree is 30-60 %, and in the second one rate is 10-2-10-4 s-1, and deformation degree is 10-30 %; isothermal holding is carried out under pressure of 10-150 MPa. ^ EFFECT: strained feed with homogenous recrystallized structure and beta-grain size of 10-30 mum; with high strength and improved coefficient of metal utilization. ^ 5 cl, 2 tbl, 1 ex |
