    Notes: Abstract The long-range diffusion of deuterium in tantalum has been investigated as a function of temperature by means of the anelastic process due to redistribution of deuterium impurities between compressed and dilated regions of the sample, under an applied stress alternating at about 4 Hz. The diffusion coefficient was found to obey an Arrhenius-type law in the temperature range 200–390 K; a deviation was observed at lower temperatures. The diffusion parameters in the exponential region areD 0D=(3.3±1.5)×10−4 cm2/s, andW D=(0.176±0.008) eV.

    A study of the effects of deuteride precipitation in tantalum by frequency and internal friction measurements (1974)

    Notes: Abstract The effects of deuteride precipitation from Ta-D solid solution was investigated by vibration frequency and internal friction measurements in the temperature range (80–300) K. Initiation of deuteride precipitation is indicated by the inflexion of the frequency curve, whereas the onset of the dislocation-loops formation around the deuteride particles is correlated with the internal friction growth (precipitation peak). The dislocation interstitial drag model which seems to better account for the precipitation peak, is discussed. The phase diagram of the Ta-D system was determined in the range of (0.2–7.5) at.∼%.
