Abstract

A vibrating wire (VW) method was applied to investigate the hydrogen absorption and desorption properties of palladium. At room temperature, a considerable shift in resonance frequency was successfully observed in VW spectra under H₂ gas exposure. The shift is reversible in the initial stage of the exposure and is attributed to changes in the density and Young's modulus of the VW sensor. Irreversibility of the shift because of embrittlement is detected after a sufficient exposure time. H absorption is slowed down enormously at T = 200K owing to suppression of the thermal activation process.
