Description
Изобретение относится к области металлургии, в частности к составам литейных сплавов на основе кобальта, которые могут быть использованы для изготовления лопаток турбореактивных двигателей.The invention relates to the field of metallurgy, in particular to compositions of cast alloys based on cobalt, which can be used for the manufacture of blades of turbojet engines.
Известен сплав на основе кобальта, содержащий, мас.%: хром ≤30,0; кремний 0-2,0; углерод ≤0,5; марганец 0-2,0; молибден ≤5,0; титан ≤4,0; медь ≤4,0; ниобий 0-1,5; кобальт - остальное [1].Known alloy based on cobalt containing, wt.%: Chromium ≤30,0; silicon 0-2.0; carbon ≤0.5; manganese 0-2.0; molybdenum ≤5.0; titanium ≤ 4.0; copper ≤ 4.0; niobium 0-1.5; cobalt - the rest [1].
Задачей изобретения является повышение прочности и твердости сплава.The objective of the invention is to increase the strength and hardness of the alloy.
Технический результат достигается тем, что сплав на основе кобальта, содержащий хром, кремний, углерод, марганец, молибден, титан, медь, ниобий, дополнительно содержит церий, магний и азот при следующем соотношении компонентов, мас.%: хром 28,0-32,0; кремний 1,0-1,5; углерод 1,0-1,5; марганец 6,0-8,0; молибден 4,0-5,0; церий 0,1-0,2; магний 0,05-1,15; титан 0,3-0,5; медь 0,3-0,5; ниобий 0,5-1,0; церий 0,1-0,1; магний 0,05-0,15; азот 0,1-0,2; кобальт - остальное.The technical result is achieved in that the cobalt-based alloy containing chromium, silicon, carbon, manganese, molybdenum, titanium, copper, niobium, additionally contains cerium, magnesium and nitrogen in the following ratio of components, wt.%: Chromium 28,0-32 0; silicon 1.0-1.5; carbon 1.0-1.5; manganese 6.0-8.0; molybdenum 4.0-5.0; cerium 0.1-0.2; magnesium 0.05-1.15; titanium 0.3-0.5; copper 0.3-0.5; niobium 0.5-1.0; cerium 0.1-0.1; magnesium 0.05-0.15; nitrogen 0.1-0.2; cobalt is the rest.
В таблице приведены составы сплава.The table shows the alloy compositions.
Сплав упрочняется в основном карбидными фазами, для чего в него вводится хром, ниобий, титан и молибден. Карбиды располагаются между осями дендритов. Марганец тормозит диффузионные процессы по границам зерен. Кремний способствует дисперсности карбидов. Твердый раствор сплава имеет гранецентрированную структуру, соответствующую γ-высокополиморфной модификации кобальта, устойчивой выше 500°С. Кроме γ-твердого раствора в сплаве, содержащем хром, присутствует твердый раствор, соответствующий ε-модификации кобальта с гексагональной структурой. Азот в химически связанном состоянии с титаном и ниобием, образует нитриды и становится легирующим элементом, улучшающим структуру сплава. При введении магния и церия оси дендритов и макрозерна размельчаются, сплав уплотняется. Медь улучшает состояние границ зерен.The alloy is hardened mainly by carbide phases, for which chromium, niobium, titanium and molybdenum are introduced into it. Carbides are located between the axes of dendrites. Manganese inhibits diffusion processes along grain boundaries. Silicon contributes to the dispersion of carbides. The alloy solid solution has a face-centered structure corresponding to a γ-highly polymorphic cobalt modification, stable above 500 ° C. In addition to the γ-solid solution in the alloy containing chromium, there is a solid solution corresponding to the ε-modification of cobalt with a hexagonal structure. Nitrogen in a chemically bound state with titanium and niobium forms nitrides and becomes an alloying element that improves the alloy structure. With the introduction of magnesium and cerium, the axis of the dendrites and macrograins are crushed, the alloy is compacted. Copper improves the state of grain boundaries.
Сплав подлежит закалке при температуре 1150-1200°С с охлаждением на воздухе и последующим старением при температуре 750-800°С в течение 16 часов.The alloy is to be quenched at a temperature of 1150-1200 ° C with cooling in air and subsequent aging at a temperature of 750-800 ° C for 16 hours.
