Conclusions
-
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.
The decomposition of the residual β-phase may be accompanied by the precipitation of titanium hydrides, which also cause embrittlement.
-
3.
The embrittlement of alloys with α+β and β-structures may be due to the embrittlement of the β-phase induced by hydrogen.
