Description

II

Известен способ термо.механичесасой обработки а+р-титановых аплавое, выключающий напрев и дефор мадию в р-области и последуЮ1щее охлаждение в воде.There is a method of thermo-mechanical treatment of a + p-titanium aplavay, which turns off the heating and deformation of the p-region and the subsequent cooling in water.

С целью Повышени  лласти чноспи и ударной ВЯЗКОСТИ полуфабрИ1каты из а+р-титановых сплавов непосредственно после деформа1ции (iB отличие от кэвестното опосОба) охлаждают со скоростью 0,1-4,0 град/мин до те;м1пературы на 100-300°С ниже темлературы а+р- -р-1превращени , выдерживают прИ этой температуре в течение 1 час и далее охлаждают со скоростью, не превышающей скорость охлаждени  на воздухе.In order to increase the power field and the impact VISCOSITY of semi-finished products from a + p-titanium alloys immediately after deformation (iB difference from quest grade) they are cooled at a speed of 0.1–4.0 deg / min to those; The temperature of the a + p-p-1 transformations is maintained at this temperature for 1 hour and then cooled at a rate not exceeding the cooling rate in air.

Обработаиные по предлагаемому способу полуфабрикаты диаметром 100 мм из спла1ва ВТ-22 и.меют следующие механические свойства:Processed by the proposed method, semi-finished products with a diameter of 100 mm from alloy VT-22 and. Have the following mechanical properties:

Предел прочности, кгм.и Удлинение, % Сужение, %Strength, kgm. And Elongation,% Narrowing,%

Предмет изобретени Subject invention

Способ тер.мо1механической обработки а+р-титановых сплавов, включающий нагрев и дефор.мацию в р-области и последующее охлаждение , отличающийс  тем, что, с целью иовышени  пластичности и ударной в зкости полуфабрикатов, о.хлаждение провод т со скоростью 0,1-4,0 град/мин до температуры на 100-300°С ниже температуры Превращени , выдержишают при этой тем.пературе в течение 1 час и Далее охлаждают со скоростью, не превыщающей скорость охлаждени  на воздухе.The method of thermal processing of a + p-titanium alloys, including heating and deformation in the p-region and subsequent cooling, characterized in that, in order to improve the ductility and impact strength of the semi-finished products, cooling is conducted at a rate of 0, 1-4.0 degrees / minute to a temperature of 100-300 ° C below the Transformation temperature, stand at this temperature for 1 hour and then cooled at a rate not exceeding the cooling rate in air.
