“…Phillips et al [30] calculated that the H/Ti ratio in the hydride increased from 1.2 to 1.5 as the applied current density was increased over the range 0.05-3.0 mA cm −2 (in 0.05 mol L −1 H 2 SO 4 ). These claims are consistent with the higher, current-dependent ratios (1.62-1.78) obtained at higher current densities (5-20 mA cm −2 ) and measured by X-ray diffraction [38]. Phillips et al found that the hydrogen absorption rate remained parabolic but increased with temperature (25-100 • C).…”

“…Previous studies 24,25) have shown that the -hydride would precipitate in the -phase matrix when the stoichiometric ratio is less than 1.56. The coexisting -phase could be the solid solution of hydrogen in -titanium.…”

“…27) Such a volume increase results in a sizable elastic and plastic constraint induced in the lattice. 28) Titanium hydrides can be prepared by gas-equilibrium, 23) direct Ti-H reaction, 24) electrolytic hydrogenation 25,[29][30][31] and vapor deposition.…”

“…Since the -hydride phase has an fcc lattice with a larger lattice (a) (b) Hydrogen-Assisted Degradation of Titanium Based Alloysconstant than the hcp lattice, hydrogen transport through this hydride is faster than through the phase. 25) In addition, hydride formation can also be significantly affected by material factors such as, alloy composition, microstructure and yield strength. 35,36) …”

Titanium base alloys are among the most important advanced materials for a wide variety of aerospace, marine, industrial and commercial applications, due to their high strength/weight ratio and good corrosion behavior. Although titanium is generally considered to be reasonably resistant to chemical attack, severe problems can arise when titanium base alloys come in contact with hydrogen containing environments. Titanium base alloys can pick up large amounts of hydrogen when exposed to these environments, especially at elevated temperatures. If the hydrogen remains in the titanium lattice, it may lead to severe degradation of the mechanical and fracture behavior of these alloys upon cooling. As a consequence of the different behavior of hydrogen in and phases of titanium (different solubility, different diffusion kinetics, etc), the susceptibility of each of these phases to the various forms of and conditions of hydrogen degradation can vary markedly. This paper presents an overview of hydrogen interactions with titanium alloys, with specific emphasis on the role of microstructure on hydrogen-assisted degradation in these alloys.

“…In either case the stoichiometry of the hydride was TiH x . Millenbach and Givon [19] indicated that the value of X increased with the cathodic charging current density. Phillips[20] and Wu [21] also indicated that X increased with increasing current density.…”
