Title: Damping capacity of Fe-Ru alloys

Abstract

In previous studies, some of the authors have reported that an Fe-17%Mn alloy undergoing non-thermoelastic {gamma}(fcc){r_arrow}{epsilon}(hcp) martensitic transformation possesses a high damping capacity, and that the damping capacity is closely related to the amount of {epsilon} martensite. Blackburn et al. investigated the transformation behaviors of Fe-Ru binary alloys, and reported that Fe-Ru alloys containing above 24%Ru (by weight) experience a {gamma}{r_arrow}{epsilon} martensitic transformation, while Fe-Ru alloys with below 19%Ru undergoes a {gamma}{r_arrow}{alpha}{prime}(bcc) martensitic transformation. it is, thus, expected that the Fe-Ru alloys which undergo a {gamma}{r_arrow}{epsilon} martensitic transformation would exhibit high damping capacity parallel to the Fe-17%Mn alloy. However, there are no studies about the damping properties of a {gamma}{r_arrow}{epsilon} martensitic Fe-Ru alloy. In the present study, the authors investigate the sampling capacity of a {gamma}{r_arrow}{epsilon} martensitic Fe-25%Ru alloy and evaluate the damping mechanisms. In addition, the damping capacity of a {gamma}{r_arrow}{alpha}{prime} martensitic Fe-13%Ru alloy is investigated in comparison with an Fe-25%Ru alloy.
