Abstract

Способ получения полуфабрикатов из сплавов на основе титана, содержащих 36 мас.% алюминия, включающий нагрев и прессование литой заготовки в металлической оболочке, отличающийся тем, что, с целью улучшения качества полуфабрикатов за счет обеспечения мелкозернистости структуры и улучшения механических свойств, перед нагревом проводят отпуск заготовки при температуре 1200…1250°C в течение 2…2,5 ч с последующим охлаждением до комнатной температуры со скоростью 5,0…7,5°C/с, а прессование осуществляют с предварительной подпрессовкой заготовки со степенью деформации 29…38% при температуре 1290…1360°C со скоростью 50…60 мм/с и степенью деформации при прессовании 90…94% с последующим охлаждением на воздухе.A method of producing semi-finished products from alloys based on titanium, containing 36 wt.% Aluminum, including heating and pressing a cast billet in a metal sheath, characterized in that, in order to improve the quality of semi-finished products by ensuring the fine grain size and improving mechanical properties, before heating, tempering blanks at a temperature of 1200 ... 1250 ° C for 2 ... 2.5 hours, followed by cooling to room temperature at a speed of 5.0 ... 7.5 ° C / s, and pressing is carried out with preliminary pressing of the workpiece with heat of deformation 29 ... 38% at a temperature of 1290 ... 1360 ° C at a speed of 50 ... 60 mm / s and the degree of deformation during pressing 90 ... 94% with subsequent cooling in air.
