Abstract
Description
Изобретение относится к области металлургии, в частности к составам сплавов на основе железа, которые могут быть использованы в машиностроении.The invention relates to the field of 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 0,15-0,2; кремний 0-2,4; никель 0-12,0; хром 0-11,0; кобальт 0-12,0; ванадий 0-12,0; алюминий 0-2,5; железо - остальное [1].A known alloy based on iron, containing, wt.%: Carbon 0.15-0.2; silicon 0-2.4; nickel 0-12.0; chrome 0-11.0; cobalt 0-12.0; vanadium 0-12.0; aluminum 0-2.5; iron - the rest [1].
Задачей изобретения является повышение ударной вязкости сплава.The objective of the invention is to increase the toughness of the alloy.
Технический результат достигается тем, что в сплаве на основе железа, содержащем углерод, кремний, никель, хром, кобальт, ванадий и алюминий, компоненты находятся при следующем соотношении, мас. %: углерод 0,2-0,4; кремний 0,03-0,05; никель 14,0-16,0; хром 0,2-0,4; кобальт 1,0-1,8; ванадий 24,0-26,0; алюминий 4,0-6,0; железо - остальное.The technical result is achieved by the fact that in an alloy based on iron containing carbon, silicon, nickel, chromium, cobalt, vanadium and aluminum, the components are in the following ratio, wt. %: carbon 0.2-0.4; silicon 0.03-0.05; nickel 14.0-16.0; chrome 0.2-0.4; cobalt 1.0-1.8; vanadium 24.0-26.0; aluminum 4.0-6.0; iron is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Ударная вязкость сплава составит 0,4-0,5 кгм/см2.Impact strength of the alloy will be 0.4-0.5 kgm / cm 2 .
Повышение ударной вязкости содержащего углерод сплава на основе железа обусловлено комплексным влиянием компонентов, входящих в его состав. Хром, никель, кобальт, ванадий, кремний упрочняют твердый раствор. Хром стабилизирует карбиды, препятствует развитию трещин при ударе. Кобальт, ванадий и алюминий увеличивают ударную вязкость сплава.The increase in toughness of the carbon-based alloy based on iron is due to the complex effect of the components that make up its composition. Chrome, nickel, cobalt, vanadium, silicon harden the solid solution. Chrome stabilizes carbides, prevents the development of cracks upon impact. Cobalt, vanadium and aluminum increase the toughness of the alloy.
Сплав может быть выплавлен в электропечах. Отливки подвергают закалке с температурой 860°С в масле, отпуску при температуре 520°С в масле.The alloy can be smelted in electric furnaces. The castings are quenched with a temperature of 860 ° C in oil, tempered at a temperature of 520 ° C in oil.
