OBTAINING TITANIUM ALLOY MATERIALS BY REDUCING TITANIUM TETRACHLORIDE Russian patent published in 2020 - IPC C22C14/00 C22B34/12 C22C1/04 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to methods of producing titanium alloy materials. Material of titanium alloy is obtained by adding TiCl₄ to incoming mixture at temperature of first reaction. Part of Ti⁴⁺ in TiCl₄ is reduced to the first intermediate mixture which contains a solution of a salt based on AlCl₃ and Ti³⁺ in form of TiCl₃ (AlCl₃)_x, where x ranges from more than 0 to 10. Reaction medium is heated to the temperature of the second reaction, wherein a portion of Ti³⁺ of the first intermediate reaction mixture is reduced to the second intermediate reaction mixture. Second intermediate reaction mixture is a solution of AlCl₃-based salt which contains Ti²⁺. Addition of TiCl₄ to the incoming mixture at temperature of the first reaction and heating to temperature of the second reaction is performed successively in the reaction process. Second reaction mixture is additionally heated to temperature of third reaction, at which Ti²⁺ forms material of titanium alloy by disproportionation reaction.

EFFECT: invention enables to obtain titanium alloy materials by improved processing techniques of the titanium tetrachloride reduction reaction in AlCl₃ based reaction media.
