Oxygen-tritium and nitrogen-tritium pairs in niobium

Long- and short-range motions of H and D in a NbMo alloy as studied by anelastic relaxations

“…Regarding the first issue it is useful to compare the strength of the relaxation investigated here with that of the peaks due to the interaction of H(D) with heavy interstitials (O,N) [21,28] or with substitutional atoms (Ti, Zr) [22,23,29] in Nb based alloys. In making this comparison, however, attention is to be paid only The origin of this extra width will be discussed later.…”

Effect of hydrogen, deuterium and oxygen on the anelastic properties of refractory alloys

“…The effect of oxygen on the hydrogen relaxation has been examined in the refractory metals (22)(23)(24)(25) in the temperature range of 4 to 100 K. Schiller et al (22) reported that the hydrogen peak height in niobium is dependent on the oxygen concentration. However to the present authors knowledge, the effect of hydrogen on the oxygen peak was not explored previously.…”

“…Internal friction spectra of hydrogen in refractory metals has been measured by many researchers. However, the previous studies have predominantly involved hydrogen in the pure metal (22)(23)(24)(25)(27)(28)(29)(30)(31)(32)(33)(34)(35). Because the hydrogen terminal solubility increases with alloy additions (3), recent interest has been in refractory alloys (36)(37)(38)(39).…”
