Physicochemical Fundamentals of a Self-Propagating High-Temperature Synthesis Process of Fabrication of Alloys Based on Rare-Earth Metals

Abstract: Проведён анализ областей применения редкоземельных металлов (РЗМ) для получения высокопрочного чугуна и конструкционных сталей. Раз-работаны физико-химические основы промышленной технологии и обо-рудование для получения сплавов РЗМ на основе СВС-процесса методом внепечной металлотермии. Получены однородные слитки многокомпо-нентных сплавов РЗМ для легирования чугуна и стали.Ключевые слова: сплавы РЗМ, восстановительная плавка, СВС-процесс, фториды, оксиды, кальций, алюминий, никель, реактор, скорость горе-ния.… Show more

“…The processes of self-propagating high-temperature synthesis (SHS) of alloys became used on an industrial scale at the end of the 20th century [9]. A special place among their diversity is occupied by reduction-type processes using uranium and rare earth fluorides when sufficient heat is released during the reaction to melt the reaction products in the solid-solid system [10]. Zirconium and niobium are refractory metals, so their losses during electron beam melting are minimal.…”
