Summary

Thermodynamics and kinetics of hydrogen absorption from the gas phase and hydrogen diffusion coefficients in the alloy were determined for three technical β-titanium alloys (Ti10- 2-3, Ti21S and Alloy C). The experiments showed that at lower temperatures hydrogen uptake is severely affected by surface oxides. At higher temperatures the uptake is controlled by diffusion. Equilibrium concentrations in the alloy increase with hydrogen partial pressure and decrease with temperature. Solubility is higher and diffusion is faster in the β-phase as compared to the α-phase.
