Description

Изобретение относится к области металлургии и касается составов сплавов на основе титана, которые могут быть использованы для изготовления деталей летательных аппаратов, труб, морской арматуры, насосов, компрессоров.The invention relates to the field of metallurgy and relates to compositions of alloys based on titanium, which can be used for the manufacture of parts for aircraft, pipes, marine fittings, pumps, compressors.

Известен сплав на основе титана, содержащий следующие компоненты, мас.%: алюминий до 8,0; молибден до 8,0; медь, кремний, железо, марганец до 15,0; титан - остальное [1].Known alloy based on titanium containing the following components, wt.%: Aluminum up to 8.0; molybdenum up to 8.0; copper, silicon, iron, manganese up to 15.0; titanium - the rest [1].

Задачей изобретения является повышение прочности сплава.The objective of the invention is to increase the strength of the alloy.

Технический результат достигается тем, что сплав на основе титана, содержащий алюминий, молибден, медь, кремний, железо, марганец, отличающийся тем, что компоненты находятся при следующем соотношении, мас.%: алюминий 7,0-7,8; молибден 8,2-8,6; медь 2,5-3,0; кремний 0,05-0,09; железо 1,5-2,5; марганец 13,0-14,0; титан - остальное.The technical result is achieved in that the titanium-based alloy containing aluminum, molybdenum, copper, silicon, iron, manganese, characterized in that the components are in the following ratio, wt.%: Aluminum 7.0-7.8; molybdenum 8.2-8.6; copper 2.5-3.0; silicon 0.05-0.09; iron 1.5-2.5; manganese 13.0-14.0; titanium - the rest.

В таблице приведены составы сплава.The table shows the alloy compositions.

Компоненты, входящие в состав сплава, проявляют себя следующим образом. Алюминий является α-стабилизатором. Молибден и кремний выполняют функцию β-стабилизаторов. Аллотропическое превращение Ti-Si происходит быстро и β-фаза закалкой не фиксируется, β-фазы Ti-Fe, Ti-Mn фиксируются закалкой.The components that make up the alloy manifest themselves as follows. Aluminum is an α stabilizer. Molybdenum and silicon act as β-stabilizers. The allotropic transformation of Ti-Si occurs quickly and the β-phase is not fixed by quenching, the β-phases of Ti-Fe, Ti-Mn are fixed by quenching.

Для сплава рекомендуется двойной отжиг: при 900°С, а затем при 600°С в течение 1 ч.Double annealing is recommended for the alloy: at 900 ° C, and then at 600 ° C for 1 h.
