Abstract
Description
Изобретение относится к области металлургии, в частности, к составам сплавов на основе никеля, которые могут быть использованы, например, для изготовления деталей двигателей, труб.The invention relates to the field of metallurgy, in particular, to compositions of nickel-based alloys, which can be used, for example, for the manufacture of engine parts, pipes.
Известен сплав на основе никеля, содержащий, мас. %: углерод 0,02-0,1; хром 20,0-25,0; кобальт 25,5-32,0; вольфрам 10,0-16,0; алюминий 0,2-0,7; элемент из группы: лантан, неодим 0,01-0,1; никель - остальное [1].Known alloy based on Nickel, containing, by weight. %: carbon 0.02-0.1; chrome 20.0-25.0; cobalt 25.5-32.0; tungsten 10.0-16.0; aluminum 0.2-0.7; an element from the group: lanthanum, neodymium 0.01-0.1; nickel - the rest [1].
Задачей изобретения является повышение термостойкости сплава.The objective of the invention is to increase the heat resistance of the alloy.
Технический результат достигается тем, что сплав на основе никеля, содержащий углерод, хром, кобальт, алюминий, элемент из группы: лантан, неодим, никель, дополнительно включает рений, гафний и ниобий, причем компоненты находятся при следующем соотношении, мас. %: углерод 0,02-0,1; хром 20,0-25,0; кобальт 10,0-15,0; алюминий 0,1-0,18; элемент из группы: лантан, неодим 0,01-0,1; рений 0,3-0,8; гафний 2,0-4,0; ниобий 2,0-4,0; никель - остальное.The technical result is achieved in that the nickel-based alloy containing carbon, chromium, cobalt, aluminum, an element from the group: lanthanum, neodymium, nickel, additionally includes rhenium, hafnium and niobium, and the components are in the following ratio, wt. %: carbon 0.02-0.1; chrome 20.0-25.0; cobalt 10.0-15.0; aluminum 0.1-0.18; an element from the group: lanthanum, neodymium 0.01-0.1; rhenium 0.3-0.8; hafnium 2.0-4.0; niobium 2.0-4.0; nickel - the rest.
В таблице приведены составы сплава на основе никеля.The table shows the compositions of the alloy based on Nickel.
В составе сплава компоненты проявляют себя следующим образом. Совместное введение в состав сплава хрома, титана, алюминия обеспечивает увеличение его жаропрочности и термостойкости за счет образования высокодисперсной интерметаллидной`γ'-фазы. Введение кобальта, рения, гафния, ниобия способствует дальнейшему увеличению жаропрочности сплава с низким содержанием углерода. Введение небольших количеств лантана или неодима также способствует повышению жаропрочности сплава.In the composition of the alloy, the components manifest themselves as follows. The joint introduction of chromium, titanium, and aluminum into the composition ensures an increase in its heat resistance and heat resistance due to the formation of a highly dispersed intermetallic γ phase. The introduction of cobalt, rhenium, hafnium, niobium further enhances the heat resistance of the low carbon alloy. The introduction of small amounts of lanthanum or neodymium also helps to increase the heat resistance of the alloy.
Сплав подвергают термообработке: нагрев в течение 2 ч при 850°С, в среде аргона и старение в течение 16 ч при 700°С, охлаждение на воздухе.The alloy is subjected to heat treatment: heating for 2 hours at 850 ° C, in argon, and aging for 16 hours at 700 ° C, cooling in air.
