Claims (4)

1. Способ изготовления тонких листов из высокопрочных титановых сплавов, включающий операции подготовки заготовки и горячую деформацию пакета заготовок в оболочке, отличающийся тем, что исходную заготовку с размером зерна α-фазы не более 2 мкм получают методом горячей прокатки кованого или штампованного сляба с относительной толщиной h3/hk=8,0-10,0, где hз - толщина исходной заготовки перед пакетной прокаткой, мм, hk - конечная толщина готовых листов, мм, затем охлаждают со скоростью 200-400°С/мин, а последующую термомеханическую обработку проводят в квазиизотермических условиях методом горячей прокатки пакета заготовок, помещенных в стальной кейс, в продольном и поперечном направлениях с разворотом на 90°, причем изменение направления прокатки осуществляют при достижении суммарной степени деформации в одном направлении 60-70%.1. A method of manufacturing thin sheets of high-strength titanium alloys, including the preparation of the workpiece and hot deformation of the package of workpieces in the shell, characterized in that the initial workpiece with an α-phase grain size of not more than 2 μm is obtained by hot rolling of a forged or stamped slab with a relative thickness h 3 / h k = 8.0-10.0, where h h is the thickness of the initial billet before batch rolling, mm, h k is the final thickness of the finished sheets, mm, then cooled at a speed of 200-400 ° C / min, and subsequent thermomechanical processing wire into quasi-isothermal conditions, by hot rolling billets package, placed in a steel case, in the longitudinal and transverse directions rotated through 90 °, wherein the change in the direction of rolling is carried out when the total degree of deformation in one direction 60-70%. 2. Способ по п.1, отличающийся тем, что величина частных обжатий при одном цикле нагрева составляет не менее 10%, причем в каждом последующем проходе не более чем в предыдущем.2. The method according to claim 1, characterized in that the magnitude of the private reductions during one heating cycle is at least 10%, and in each subsequent pass no more than in the previous one. 3. Способ по п.1, отличающийся тем, что температура каждого последующего прохода прокатки не превышает предыдущую.3. The method according to claim 1, characterized in that the temperature of each subsequent rolling pass does not exceed the previous one. 4. Способ по пп.1-3, отличающийся тем, что температуру горячей деформации пакета заготовок устанавливают в диапазоне Тпп-(200-300)°С.4. The method according to claims 1 to 3, characterized in that the temperature of the hot deformation of the package of blanks is set in the range of TPP- (200-300) ° C.
