The phase composition and structure of powders of titanium sponge exposed to
processes of chemical and thermal processing is investigated.
As a result of X-ray analysis, it is found that after hydrogenation titanium powder consists of
TiH2±х phase, while with the increase in the degree of phase dehydrogenation the percentage of
TiH2±х decreases, and under perfect the dehydrogenation the structure consists mainly of α-Ti.
Particle size analysis revealed that the partially dehydrated powders have the least degree of
polydispersity.
It is established that by means of regulation of technological regimes of hydrogenationdehydrogenation
the two-phase structure with different ratios of α-phase to TiH2±х can be
synthesized.
It is shown that the presence of titanium hydride contributes to stabilization of the structure of
formed powders.
