Conclusions
-
1.
It is shown that impregnation of titanium alloys to hydrogen contents of 0.8% or more results in the precipitation of coarse titanium hydride particles which act as metal rupture centers.
-
2.
It was established that hydrogen contents of more than 0.2% produce a marked fall in the mechanical properties of titanium alloys. High hydrogen concentrations in such alloys lead to the appearance of micro- and macrocracks.
-
3.
The particle-size distribution and particle shape of the resultant powder are determined by the amount of hydrogen and its distribution in the metal and the parameters of the comminution process.
