Fe-Mn alloys with non-thermoelastic fcc({gamma}){r_arrow}hcp({epsilon}) martensitic transformation have become attractive as the subject of many investigations due to their high damping characteristics. In previous works, some of the authors have reported that the damping capacity of an Fe-17% Mn alloy depends on the amount of {epsilon} martensite, and that the movement of various boundaries associated with {gamma}/{epsilon} interfaces may give rise to a high damping capacity. In order to develop these alloys for engineering application, the role of carbon, which is an unavoidable impurity added during the industrial manufacturing processes, in the damping properties must be thoroughly understood. As part of a study on the practical application of Fe-Mn alloys, the present work aims to report the change in damping capacity with aging time and temperature for Fe-17% Mn alloys with various carbon contents, and to discuss the role of carbon impurity in the damping properties from a kinetic point of view.
