  • Titanium master alloy for titanium-aluminum based alloys
    Patent number: 11959185
    Abstract: A process is disclosed for the electro-refinement of titanium aluminides to produce titanium-aluminum master alloys which process is effective even in the presence of substantial amounts of aluminum and in the presence of ten (10) or more weight percent oxygen in the material(s) to be refined. The process is likewise effective without the addition of titanium chlorides or other forms of soluble titanium to the electrolyte bath comprising halide salts of alkali metals or alkali-earth metals or a combination thereof.
    Type: Grant
    Filed: July 1, 2022
    Date of Patent: April 16, 2024
    Assignee: UNIVERSAL ACHEMETAL TITANIUM, LLC
