The Ti 2 Cu interaction with hydrogen is determined to be possible in the destructive hydrogenation (DH) region. The Ti 2 Cu DH process is realized at the temperatures 373, 473, 573, 773 and 973 K. Its products were titanium dihydride and copper-rich with regard to Ti 2 Cu intermetallic phases as well as the copper against the absorbed hydrogen amount. The mechanism of the Ti 2 Cu destructive hydrogenation consists in the following: hydrogen selectively interacts with titanium which leaves from the Ti 2 Cu composition, according to the scheme: β-TiH y (bct-bcc) → TiH 1,92 (fcc). The copper-riched intermetallic phases form after such titanium amounts leaves from Ti 2 Cu composition which support the formation of a new Ti:Cu stoichiometric ratio according to the Ti–Cu state diagram.
