Correlations of phase relationships of metal-hydrogen systems with internal friction phenomena

Changes with increasing hydrogen content (Hn) in the form of the temperature T dependences of elastic energy dissipation (internal friction) over the range of 90–300 K at about 3 kHz have revealed two well-defined Q−1 peaks in the Q−1−T plots that have been associated with stress-assisted rearrangem...

Summary:Changes with increasing hydrogen content (Hn) in the form of the temperature T dependences of elastic energy dissipation (internal friction) over the range of 90–300 K at about 3 kHz have revealed two well-defined Q−1 peaks in the Q−1−T plots that have been associated with stress-assisted rearrangements of hydrogen interstitials in the bulk lattices of palladium and palladium-silver alloys. Combined with information concerning hydrogen content dependences of other physical properties of the Pd-Ag-H system, the data obtained from the studies of internal friction have shown an indication of providing valuable guidance concerning structural correlations with the phase relationships and hydrogen content dependences of physical and thermodynamic parameters of these and other metal-hydrogen systems.
