Изобретение относится к области цветной металлургии и может быть использовано при термообработке листов и ленты из титановых бета-сплавов, изготовленных методом прокатки. Изобретение направлено на ликвидацию коробоватости листов, достижение высокой планшетности и высокого угла изгиба в отожженном состоянии с одновременным повышением характеристик МЦУ в состаренном состоянии при сохранении уровня прочности. Поставленная задача решается за счет того, что после горячей прокатки проводят дополнительную механическую зачистку слитка и травление, теплую прокатку проводят при Т<Mv>п.п<D>, равной -(30-100)°С в два этапа, причем на первом этапе со степенью деформации 50-90%, на втором этапе со степенью деформации 3-15%, а между теплыми прокатками осуществляют холодную прокатку. В конце обработки проводят вакуумный отжиг при температуре T<Mv>п.п<D>, равной +(30-70)°С с выдержкой 0,25-2,0 ч, и охлаждением до 600°С со скоростью 1-100°С/мин и далее до 250<198>C со скоростью 6-50°С/мин. Кроме того, после первой теплой прокатки проводят дополнительный вакуумный отжиг при той же температуре, но с выдержкой 0,5-4,0 ч, и охлаждением с 600 до 250<198>С со скоростью 5-100°С/мин, а холодную прокатку осуществляют с суммарной степенью деформации 15-70%.The invention relates to the field of non-ferrous metallurgy and can be used in the heat treatment of sheets and bands of titanium beta alloys made by rolling. The invention is aimed at eliminating the warping of sheets, achieving high flatness and a high bending angle in the annealed state while improving the characteristics of the MCU in the aged state while maintaining the level of strength. The problem is solved due to the fact that after hot rolling an additional mechanical cleaning of the ingot and etching is carried out, warm rolling is carried out at T <Mv> pp <D>, equal to - (30-100) ° С in two stages, and at the first stage with a degree of deformation of 50-90%, in the second stage with a degree of deformation of 3-15%, and cold rolling is carried out between warm rolling. At the end of the treatment, vacuum annealing is carried out at a temperature T <Mv> p.p <D> of + (30-70) ° С with a holding time of 0.25-2.0 hours and cooling to 600 ° С at a speed of 1-100 ° C / min and further to 250 <198> C at a rate of 6-50 ° C / min. In addition, after the first warm rolling, additional vacuum annealing is carried out at the same temperature, but with a holding time of 0.5-4.0 hours, and cooling from 600 to 250 <198> C at a speed of 5-100 ° C / min, and cold rolling is carried out with a total degree of deformation of 15-70%.
