Abstract

Abstract: The hydrogen sorption and desorption behavior in spherical powder of pure titanium used for additive manufacturing have been investigated. The dependencies of oxide dissolution time and hydrogen sorption rate on pressure and temperature have been obtained. The main regularities of phase formation in titanium powder during hydrogenation until hydrogen concentration 4 wt% have been showed. The peculiarities of hydrogen desorption from the spherical powder of titanium with hydrogen concentration 4 wt% have been demonstrated. Graphical abstract: Highlights: The spherical titanium powder is characterized by low resistance to hydrogen sorption. The growth of hydrogen rate with temperature and pressure increase is almost linear. The dislocations emerge on particles surface at hydrogenation-dehydrogenation process.
