Thermal desorption spectroscopy (TDS)—Application in quantitative study of hydrogen evolution and trapping in crystalline and non-crystalline materials

Hydrogen accumulation and distribution during the saturation of a VT1-0 titanium alloy by an electrolytic method and from a gas atmosphere

“…6) [10]. As a result, we obtained the following binding energies of hydrogen: 108 kJ/mol for electrolytic saturation and 102 kJ/mol for gas phase saturation.…”

“…To determine the state and quantity of hydrogen accumulated in metals, researchers apply thermodes orption spectroscopy (TDS), where the flow of des orbed hydrogen is continuously measured in heating at a given rate [10,11]. In the TDS studies of hydrogen accumulation in titanium alloys, it is important to take into account the effect of the phase transitions in the titanium-hydrogen system on thermally stimulated hydrogen desorption, since they affect the shape of TDS spectra [8,12].…”

“…In the TDS studies of hydrogen accumulation in titanium alloys, it is important to take into account the effect of the phase transitions in the titanium-hydrogen system on thermally stimulated hydrogen desorption, since they affect the shape of TDS spectra [8,12]. The hydrogen accumulation in titanium was analyzed by TDS in many works [8][9][10][11][12]. For example, the effect of the phase transitions in the titanium-hydrogen system on the thermally stimu lated hydrogen desorption after electrolytic hydrogen saturation was comprehensively studied in [12].…”

“…For example, the effect of the phase transitions in the titanium-hydrogen system on the thermally stimu lated hydrogen desorption after electrolytic hydrogen saturation was comprehensively studied in [12]. The authors of [9,10] investigated the hydrogen accumu lation in titanium by TDS during saturation from a gas atmosphere; however, they did not analyze the effect of the phase transitions in the titanium-hydrogen sys tem on thermally stimulated hydrogen desorption after saturation from a gas atmosphere.…”

Kinetics of Hydrogen Desorption from Rapidly Solidified Al-Cr Alloys

“…The thermal desorption analysis represents a modern approach to this problem and can be regarded as a superior technique because of its sensitivity and the accuracy of measurements. 14,15) To monitor surface morphology of the foils we employed atomic force microscopy (AFM) and scanning electron microscopy (SEM). It should be noticed that initial research 16,17) on H desorption processes in RS aluminum and preliminary results obtained for its lightly doped RS binary alloys with Ti, Cr and Zr have clearly demonstrated a great difference between hydrogen behavior in RS aluminum foils and one in traditionally processed aluminum samples.…”
