The First Investigation of Tantalum Impurity Influence on Deuterium Retention in W–Ta Alloy after Gas Exposure

This article presents the results of the first investigation of deuterium retention in W and W– x Ta monocrystalline alloys ( x = 1, 3, 5, at %). Exposure in gaseous deuterium was performed in the temperature range of 425–625 K at the pressure of 10 3 Pa. The results of thermal desorption spectrosco...

Zusammenfassung:This article presents the results of the first investigation of deuterium retention in W and W– x Ta monocrystalline alloys ( x = 1, 3, 5, at %). Exposure in gaseous deuterium was performed in the temperature range of 425–625 K at the pressure of 10 3 Pa. The results of thermal desorption spectroscopy (TDS) of deuterium retention in samples are presented.
