Conclusions
-
1.
Commercial α titanium alloys with 0.01–0.03% H have a complex phase composition and contain precipitates of saturated and unsaturated cubic hydrides, and also regions of the matrix supersaturated with hydrogen.
-
2.
Under ordinary conditions, no hydrides are precipitated in α+β alloys with the same hydrogen concentration. Titanium hydrides may be precipitated during welding and with application of stresses in zones with an elevated hydrogen content.
-
3.
Precipitation of titanium hydrides favors stabilization of microstresses in the lattice of α titanium.
