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  m. Thermocycling curves were obtained in a wide range of temperatures and concentrations for - and -titanium. Evaluations of the kinetic parameters of absoprtion and desoprtion as well as the heat of sorption in - and -titanium are presented.
