Abstract
Structural phase transformations of the hcp → bcc → fct → fcc → fct (α → β → γ → δ → ε) type in titanium hydrides TiH x experimentally found to occur with increase in the hydrogen concentration x are studied theoretically. Free energy phases are statistically calculated, and their concentration dependence is determined. Phase transformation temperatures are found from intersection points of free energy curves and from points of common tangents to the curves. The energy parameters of the system are estimated. The calculation results are compared with the experimental data.
