Claims (1)

Способ изготовления плит из титановых сплавов, включающий нагрев заготовки до температуры прокатки, горячую прокатку и термообработку плит, отличающийся тем, что после нескольких стадий горячей прокатки в (α+β)-области заготовку подвергают дополнительной обработке, а именно: нагревают до температуры на 50-150°С выше температуры полиморфного превращения, выдерживают в течение 15-50 мин и охлаждают со скоростью, по крайней мере, 50°С/мин, затем заготовку нагревают до температуры на 60-180°С ниже температуры полиморфного превращения и прокатывают в продольном или продольно-поперечном направлении относительно направления прокатки исходной заготовки с суммарной степенью деформации, по крайней мере, 75%, после чего плиту подвергают термообработке путем отжига при температуре 700-850°С с выдержкой 30-90 мин.A method of manufacturing plates from titanium alloys, including heating the workpiece to a rolling temperature, hot rolling and heat treatment of the plates, characterized in that after several stages of hot rolling in the (α + β) region, the workpiece is subjected to additional processing, namely: it is heated to a temperature of 50 -150 ° C above the temperature of the polymorphic transformation, incubated for 15-50 minutes and cooled at a speed of at least 50 ° C / min, then the workpiece is heated to a temperature of 60-180 ° C below the temperature of the polymorphic transformation and rolled into longitudinal or longitudinal-transverse direction relative to the direction of rolling of the original billet with a total degree of deformation of at least 75%, after which the plate is subjected to heat treatment by annealing at a temperature of 700-850 ° C with a shutter speed of 30-90 minutes
