Abstract

Anelastic behaviour was studied in hydrogenated Inconel 600 alloy. Two complex peaks were detected in the temperature range 80–500 K. The low-temperature peak (100–270 K) was recognized as a hydrogen-induced Snoek-like relaxation peak, while the high-temperature peak may be caused by some transient processes. The low-temperature peak is attributed to the transition of hydrogen atoms between the energetically equivalent octahedral sites, which defines the fine structure of the peak. Non-monotonic dependence of the peak height on the charging current density indicates the possible formation of hydride phases.
