Hydrogen transport behavior of Timetal-21S alloyUse is made of the thermogravimetric-analysis method to ascertain the hydrogen-transport characteristics of the Timetal-21S beta-Ti alloy, at pressures of up to 50 torr over the 400-800 C temperature range. Hydrogen solubility is found to be high; the equilibrium hydrogen concentration is noted to deviate from Sievert's law at higher pressures. These deviations are likely associated with hydrogen-induced microstructural changes in the alloy, and the kinetics of hydrogen uptake reflect these changes.
