Abstract

Впервые получены и исследованы высокоэнтропийные сплавы систем CrNbMoVW и CoCrFeNiMnW. Установлены физико-химические закономерности механохимического синтеза, определены особенности формирования микроструктуры и фазового состава в зависимости от энергонапряженности процесса механохимического синтеза. Определены процессы эволюции микроструктуры и фазового состава в процессе консолидации порошков под воздействием различных источников теплоты, механические свойства консолидированных образцов. Получена модельная порошковая проволока и разработана технология электродуговой наплавки с ее использованием.

High-entropy alloys of the CrNbMoVW and CoCrFeNiMnW systems have been obtained and studied for the first time. The physicochemical regularities of mechanochemical synthesis have been established, the features of the microstructure and phase composition formation have been determined depending on the energy intensity of the mechanochemical process. The evolution of the microstructure and phase composition in the powder consolidation process under influence of various heat sources and the mechanical properties of consolidated samples have been determined. A model flux-cored wire and technology of electric arc surfacing using flux-cored wire was developed.
