The internal friction of deformed vanadium has been measured in a torsion pendulum over a temperature range between −190 and +300°C. The oxygen and hydrogen contents are monitored for individual wire specimens by measuring the height of the oxygen Snoek peak and the position of the precipitation peak (or self-twisting) associated with the hydride precipitation.
It is concluded that the presence of hydrogen is essential for the appearance of the α-peak.
