EFFECT: optimised process of producing composite cylindrical workpieces, increase in the tensile strength of the reinforced section of the bladed disk, reduction in the weight of turbine parts. 5 cl, 12 dwg, 3 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 761 530 C1 (51) МПК C22C 47/20 (2006.01) C22C 47/02 (2006.01) C22C 49/11 (2006.01) C22C 49/14 (2006.01) C22C 101/14 (2006.01) C22C 121/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C22C 47/20 (2021.05); C22C 47/02 (2021.05); C22C 49/11 (2021.05); C22C 49/14 (2021.05); F16C 2220/00 (2021.05) (21)(22) Заявка: 2020140702, 10.12.2020 10.12.2020 Дата регистрации: 09.12.2021 (45) Опубликовано: 09.12.2021 Бюл. № 34 2 7 6 1 5 3 0 R U (56) Список документов, цитированных в отчете о поиске: WO 2017137262 A1, 17.08.2017.
