Study of the kinetics of hydrogen sorption and desorption from titanium

A method of thermocycling in a hydrogen medium for studying the kinetics of the interaction between hydride-forming metals and hydrogen is proposed. The method is applied to the titanium powder with a grain size of 15-20 μ m. Thermocycling curves were obtained in a wide range of temperatures and concentrations for α- and β-titanium. Evaluations of the kinetic parameters of absoprtion and desoprtion as well as the heat of sorption in α- and β-titanium are presented.
