Description

Изобретение относится к области черной металлургии, в частности к составам сплавов на основе железа, которые могут быть использованы в машиностроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of alloys based on iron, which can be used in mechanical engineering.

Известен сплав на основе железа, содержащий, мас. %: углерод 0,9-1,4; кремний 0,3-0,9; марганец 7,0-13,0; ванадий 0,01-0,35; хром 0,2-1,0; азот 0,01-0,06; кальций 0,001-0,02; РЗМ 0,002-0,05; железо - остальное [1].Known alloy based on iron, containing, by weight. %: carbon 0.9-1.4; silicon 0.3-0.9; manganese 7.0-13.0; vanadium 0.01-0.35; chrome 0.2-1.0; nitrogen 0.01-0.06; calcium 0.001-0.02; REM 0.002-0.05; iron - the rest [1].

Задачей изобретения является снижение склонности сплава к трещинообразованию.The objective of the invention is to reduce the tendency of the alloy to crack formation.

Технический результат достигается тем, что сплав на основе железа, содержащий углерод, кремний, марганец, ванадий, хром, кальций, РЗМ, в качестве РЗМ содержит самарий и дополнительно - вольфрам при следующем соотношении компонентов, мас. %: марганец 5,5-6,5; ванадий 0,06-0,1; хром 0,2-0,4; кальций 0,001-0,002; самарий 0,07-0,11; вольфрам 1,0-1,4; железо - остальное.The technical result is achieved in that the iron-based alloy containing carbon, silicon, manganese, vanadium, chromium, calcium, rare-earth metals, contains rare earth as samarium and additionally tungsten in the following ratio of components, wt. %: manganese 5.5-6.5; vanadium 0.06-0.1; chrome 0.2-0.4; calcium 0.001-0.002; samarium 0.07-0.11; tungsten 1.0-1.4; iron is the rest.

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

Критическая нагрузка образования трещин в сплаве составит ~70 кг, а суммарный размер трещин ~5 мм для всех приведенных в таблице составов.The critical load of cracking in the alloy is ~ 70 kg, and the total crack size is ~ 5 mm for all the compositions listed in the table.

Кобальт улучшает металлическую основу сплава. Хром, марганец, вольфрам, ванадий снижают склонность сплава к трещинообразованию при механических нагрузках. Ванадий, кальций, самарий способствуют получению мелкозернистой структуры сплава.Cobalt improves the metal base of the alloy. Chrome, manganese, tungsten, vanadium reduce the tendency of the alloy to crack under mechanical stress. Vanadium, calcium, samarium contribute to obtaining a fine-grained alloy structure.

Сплав может быть выплавлен в электропечах.The alloy can be smelted in electric furnaces.
