    The results of researches made at creation of technology of production of super-large single crystals of tungsten in the form of plates and bodies of rotation are presented in E.O. Paton Electric Welding Institute NAS of ...
  • Suppression of segregation and control of the structure of ingots and casting 
    Shapovalov, V.O.; Grigorenko, G.M.; Nikitenko, Yu.O.; Yakusha, V.V.; Shapovalov, E.V. (Вопросы атомной науки и техники, 2020)
    The problem of segregation in large ingots, which are used in energy, heavy engineering, etc., is considered. A new approach to suppressing segregation processes is proposed. It consists in regulating the local crystallization ...
