Изобретение относится к области композиции литейных жаропрочных сплавов на никелевой основе, предназначенных для изготовления отливок, например, рабочих и сопловых лопаток газотурбинных двигателей с равноосной и направленной структурой. Задачей изобретения является повышение термической усталости металла при сохранении его жаропрочности. Поставленная цель достигается посредством дополнительного введения в сплав одного элемента из группы, включающей иттрий и скандий. Использование изобретения позволит в 3-4 раза повысить термическую усталость сплава и соответственно в 2-3 раза увеличить ресурс работы лопаток газотурбинных авиационных двигателей.The invention relates to the field of composition of casting heat-resistant nickel-based alloys intended for the manufacture of castings, for example, working and nozzle blades of gas turbine engines with equiaxed and directional structure. The objective of the invention is to increase the thermal fatigue of the metal while maintaining its heat resistance. This goal is achieved by the additional introduction into the alloy of one element from the group comprising yttrium and scandium. Using the invention will allow 3-4 times to increase the thermal fatigue of the alloy and, accordingly, 2-3 times to increase the service life of the blades of gas turbine aircraft engines.
