STUDY OF SNOEK-TYPE RELAXATION IN HYDROGENATED INCONEL-600

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