Abstract

FIELD: tungsten-base alloys applicable in manufacture of rocket nozzles, thermocouples, reactor components, electric heating elements and lamp filaments. SUBSTANCE: tungsten-base alloy has the following qualitative and quantitative composition, mas. molybdenum 10.0-20.0; zirconium 0.1-0.2; nickel 1.0-2.0; chromium 10.0-20.0; aluminium 3.0-5.0; the balance, tungsten. Tungsten-base alloy features heat resistance (mass loss) of 75% EFFECT: higher service properties. 1 tbl

Description

Изобретение относится к области металлургии и касается составов сплавов на основе вольфрама, используемых для изготовления ракетных сопел, термопар, деталей реакторов, электронагревательных элементов и тел накала. The invention relates to the field of metallurgy and relates to compositions of tungsten-based alloys used for the manufacture of rocket nozzles, thermocouples, reactor parts, electric heating elements and heat bodies.

Известны различные сплавы на основе вольфрама, в числе которых сплав, содержащий, мас. молибден 25,0; цирконий 0,11; углерод 0,05; вольфрам остальное [1, 2]
Цель изобретения повышение жаростойкости сплава.Various alloys based on tungsten are known, including an alloy containing, by weight. molybdenum 25.0; zirconium 0.11; carbon 0.05; tungsten rest [1, 2]
The purpose of the invention is to increase the heat resistance of the alloy.

Цель достигается тем, что в состав сплава, содержащего молибден, цирконий, вольфрам, дополнительно вводят никель, хром, алюминий, при следующем соотношении компонентов, мас. молибден 10,0-20,0; цирконий 0,1-0,2; никель 1,0-2,0; хром 10,0-20,0; алюминий 3,0-5,0; вольфрам остальное. The goal is achieved by the fact that in the composition of the alloy containing molybdenum, zirconium, tungsten, nickel, chromium, aluminum are additionally introduced, in the following ratio of components, wt. molybdenum 10.0-20.0; zirconium 0.1-0.2; nickel 1.0-2.0; chrome 10.0-20.0; aluminum 3.0-5.0; tungsten rest.

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

Сплав может быть получен вакуумной плавкой в электродуговых или электроннолучевых печах. При изготовлении фасонных отливок сложной конфигурации плавление металла осуществляется в гарнисаже, разливка производится центробежным способом в графитовую изложницу. The alloy can be obtained by vacuum melting in electric arc or electron beam furnaces. In the manufacture of shaped castings of complex configuration, the metal is melted in the skull, the casting is carried out by a centrifugal method in a graphite mold.
