Definitions

  • the present disclosure relates to a method to produce titanium master alloy for titanium-aluminum based metal alloys.
  • titanium alloys are produced from titanium “sponge”, the product of a process known as the “Kroll Process”. In subsequent steps, aluminum and other alloying metals must be added to the sponge by using various melting processes. Therefore, the cost of titanium alloys is several times higher than the original cost of titanium. For example, in one 2015 publication, titanium production cost is indicated to be $9.00/kg (Ma Qian and Francis H. Froes, ed., Titanium Powder Metallurgy Science, Technology and Application (Elsevier Inc., 2015), p. 37)) whereas the cost of Ti—Al—V is $17.00/kg.
  • titanium and its alloys are the only choice for many engineering applications. 90% of titanium that is used in the aerospace industry is used as titanium alloys. Accordingly, there is a need for a new titanium alloy production process that reduces the cost significantly.
  • titanium chlorides are produced by carbo-chlorination of highly purified TiO 2 . Therefore, the use of these titanium chlorides adds more cost to the refining process.
  • titanium-aluminum alloys e.g. master alloys
  • the methods provide a simple and more economical way to produce titanium-aluminum based alloys. With one or more embodiments of the instant disclosure, these methods do not require the addition of any soluble titanium (such as titanium chlorides) to the electrolyte, which thereby further reduces production cost.
  • the present disclosure provides for alloy products (e.g. Ti—Al master alloys) that are lightweight and “wool-like” or powdery products.
  • alloy products e.g. Ti—Al master alloys
  • the temperature and composition of the electrolyte bath appears to influence the physical form of the titanium-aluminum master alloy formed on the cathode. Temperatures in the range of 550-650° C. tend to result in a fine powdery texture, while temperatures in the range of 650-750° C. produce a product with a wool-like morphology, and temperatures in the range of 750-850° C. produce a crystalline product.
