Conclusions

  1. 1.

    Hydrogen accelerates the eutectoid decomposition of the β-phase, with the precipitation of chemical compounds in alloys with α+β and β′ structures. The embrittlement of these alloys is induced by the presence of brittle intermetallic compounds.

  2. 2.

    The decomposition of the residual β-phase may be accompanied by the precipitation of titanium hydrides, which also cause embrittlement.

  3. 3.

    The embrittlement of alloys with α+β and β-structures may be due to the embrittlement of the β-phase induced by hydrogen.
