Abstract

Internal friction (IF) in hydrogenated Inconel-600 alloy was studied. Two complex peaks:were detected in the temperature range of 80-500 K due to hydrogen charging. The low-temperature peak, 100-270 K, was recognized:as a hydrogen-induced Snoek-like relaxation peak, while the high-temperature peak, 270-500 K, Is obviously::caused by transition processes. The low-temperature peak is caused by transitions or jumps of hydrogen atoms between the energetically equivalent octahedral-sites, which defines the fine structure of the peak. The high-temperature peak is associated with hydride decomposition on heating. Non-monotonous dependence of the high-temperature peak height on the charging current density reveals the formation of hydride phase.
