Claims (2)

1. Способ изготовления промежуточной заготовки из α- и α+β-титановых сплавов, включающий ковку слитка в пруток за несколько переходов при температуре β- и (α+β)-области, механическую обработку заготовки и окончательное прессование в (α+β)- области, отличающийся тем, что величина укова на последних переходах ковки составляет 1,36-2,5, а нагрев заготовки перед прессованием осуществляют в два этапа, причем на первом этапе заготовку нагревают до температуры поверхности заготовки в диапазоне от температуры на 250°С ниже температуры полиморфного превращения до температуры на 100°С выше температуры полиморфного превращения со скоростью 0,3-2,5°С/с, а на втором этапе заготовку охлаждают или нагревают до температуры на 40-250°С ниже температуры полиморфного превращения.1. A method of manufacturing an intermediate billet from α- and α + β-titanium alloys, including forging an ingot into a bar in several transitions at a temperature of β- and (α + β) -regions, machining the billet and final pressing in (α + β) - area, characterized in that the size of the yoke at the last forging transitions is 1.36-2.5, and the workpiece is heated before pressing in two stages, and at the first stage, the workpiece is heated to the surface temperature of the workpiece in the range of 250 ° C. lower than polymorphic temperature they are brought to a temperature 100 ° C higher than the polymorphic transformation temperature at a rate of 0.3-2.5 ° C / s, and in the second step, the workpiece is cooled or heated to a temperature 40-250 ° C lower than the polymorphic transformation temperature. 2. Способ по п.1, отличающийся тем, что на первом этапе заготовку нагревают в индукционной печи.2. The method according to claim 1, characterized in that in the first stage the preform is heated in an induction furnace.
