The First Investigation of Tantalum Impurity Influence on Deuterium Retention in W–Ta Alloy after Gas Exposure
https://doi.org/10.56304/S2079562922010080
Abstract
This article presents the results of the first investigation of deuterium retention in W and W–xTa 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 103 Pa. The results of thermal desorption spectroscopy (TDS) of deuterium retention in samples are presented.
