Titanium powder, carbon (carbon black) in a ratio corresponding to equiatomic titanium carbide and high speed steel as a thermally inert binder was used as a reaction mixture. It was found that the mass transfer of reaction mixture components between the carbide and metal binder was taking place during synthesis, as a result of which the final phase and elemental composition of the synthesis products was formed. It is shown that the volume content of thermally inert binder significantly affects the dispersion of the formed carbide phase..Аудитория: .Тематика: электронный ресурс | труды учёных ТПУ | порошки | самораспространяющийся высокотемпературный синтез | композитные порошки | быстрорежущие стали | карбид титана | рентгеноструктурный анализ | СВС Ресурсы он-лайн:Щелкните здесь для доступа в онлайнTitle screen
