Thermochemical investigation of the change in the enthalpy of titanium on its transition into the dehydrogenated state

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    A pyknometric study was carried out of the correlation between the composition and density of compact hydrogenated and dehydrogenated titanium. It is shown that the dehydrogenation process proposed in the present work preserves “the vacancy picture of the hydrogenation process” in titanium.

  2. 2.

    Using a thermochemical method, a study was made of the change in the enthalpy of titanium on its transition into the dehydrogenated state. A formula has been derived for the approximate calculation of the change in the isobaric-isothermal potential of titanium on its transition into the dehydrogenated state.

  3. 3.

    The effect was studied, by Deryagin's technique, of hydrogenation and dehydrogenation on the specific surface of titanium powder.

  4. 4.

    Dehydrogenated titanium was examined by electron microscopy.

  5. 5.

    It is concluded that, since titanium powder prepared by the technique of hydrogenation and subsequent outgassing exhibits high surface activity and has a mobile lattice, it is superior to powders manufactured by other processes in powder metallurgical applications.
