- Abstract
- Interrupted thermal desorption and X-ray diffraction techniques were used to study the effect of graphite and boron additives on non-equilibrium decomposition of mechanically activated commercial TiH2. The phase transformation sequence is described as a number of consecutive reactions corresponding to desorption peaks. The process is compared to non-equilibrium decomposition of commercial TiH2. The mechanical pre-treatment with additives significantly eases and accelerates decomposition of TiH2 to alpha Ti(H), but hinders the stage of alpha Ti( H) -> alpha Ti transformation. Only a small portion of pure alpha Ti was detected for as-milled TiH2 and TiH2/B powders after the final TPD. No alpha Ti was formed in the case of as-milled TiH2/C. (C) 2011 Elsevier B.V.
