OBTAINING TITANIUM ALLOYS BY REDUCING TITANIUM TETRAHALIDES Russian patent published in 2020 - IPC C22C14/00 C22B34/12 C22B5/04 B22F9/18 

FIELD: metallurgy.

SUBSTANCE: invention relates to production of titanium alloy Ti-Al. Initial mixture containing aluminum, possibly AlCl₃ and optionally one or more halogenides of alloying element, is heated to preheating temperature, then introduced into initial mixture of TiCl₄ at a first reaction temperature to substantially reduce substantially Ti⁴⁺ in TiCl₄ to Ti³⁺, then heating to second reaction temperature to substantially reduce total Ti³⁺ to Ti²⁺ to obtain an intermediate mixture which contains a Ti²⁺ salt, and introducing the intermediate mixture into the reaction chamber at a disproportionation reaction temperature to obtain Ti²⁺ titanium alloy by disproportionation reaction.

EFFECT: obtaining titanium-aluminum alloy by reducing titanium tetrachloride.
