  • Patent number: 9067264
    Abstract: The invention relates to energy-saving manufacturing of purified hydrogenated titanium powders or alloying titanium hydride powders, by metallo-thermic reduction of titanium chlorides, including their hydrogenation, vacuum separation of titanium hydride sponge block from magnesium and magnesium chlorides, followed by crushing, grinding, and sintering of said block without need for any hydro-metallurgical treatment of the produced powders. Methods disclosed contain embodiments of processes for manufacturing high purity high-purity powders and their use in manufacturing near-net shape titanium and titanium-alloy articles by sintering titanium hydride and alloyed titanium hydride powders produced from combined hydrogen-magnesium reduction of titanium chlorides, halides and hydrides of other metals.
    Type: Grant
    Filed: May 24, 2012
    Date of Patent: June 30, 2015
    Inventors: Vladimir S. Moxson, Volodymyr A. Duz, Andrey G. Klevtsov, Viktor D. Sukhoplyuyev, Mihajlo D. Sopka, Yury V. Shuvalov, Mykhailo Matviychuk

  • Patent number: 8007562
    Abstract: The cost-effective hydrogenated, purified titanium powder is manufactured by the semi-continuous process including: (a) magnesium-thermic reduction of titanium chlorides at 830-880° C. in the hydrogen atmosphere characterized by the formation of a hollow porous block of the reaction mass having an open cavity in the center of the block, (b) full thermal-vacuum separation of the hollow block from excessive Mg and MgCl2 at 850-980° C. and residual pressure of 26-266 Pa using a multi-step cycle including: (i) purging hydrogen at 800-950° C. into the reactor at the pressure 10 kPa to 24.
