“…The MMD effect has found a broad application for the materials based on ferro-and ferrimagnetic alloys. The study of MMD and the development of new damping materials have important prospects for using in microelectronic devices [3] and for vibration isolation of precision instruments [4][5][6]. Acoustomagnetic labels, used for electronic tracking of goods, are one of the first examples of its application [7]; see Fig.…”

This review is devoted to the analysis of three components of magneto-mechanical damping (MMD), namely, macroeddy, microeddy, and hysteresis components, in ferromagnetic alloys. Theoretical models and equations for all three components of the MMD are discussed. The application of the classical theory of micro- and macroeddy MMD to determine the influence of the frequency of cyclic external mechanical load on the damping ability of the material is shown. A discussion on the role of various factors, such as temperature, strain amplitude, vibration frequency, and external magnetic field, on the magnitude of the MMD is provided.

“…For example, recently damping variations depending on microstructural features (dislocations, stacking faults and twins) in extruded pure Mg after plastic deformation and subsequent annealing treatments have been investigated by Kim and Park [33] while Tang et al [34] studied the effect of Y content in extruded Mg. The effects of the annealing temperature on damping in an Fe11Cr-2.5Mo-0.1Zr-1.0Ni forged alloy have been investigated by Chen et al [35].…”

The AA7050 alloy prepared through the standard industrial hot-forging cycle has been investigated by means of isothermal mechanical spectroscopy (MS) from room temperature up to 185 °C. Each MS test consisted of a cycle with two stages, at increasing and decreasing strain. After each cycle the damping value resulted to be higher than the original one indicating the occurrence of an irreversible transformation. Such phenomenon, observed for all the test temperatures, becomes more relevant for T ≥ 150 °C. The irreversible transformation has been discussed and explained by considering the evolution of the mean dislocation link length between pinning points represented by nanometric MgZn2 precipitates. The breakaway of dislocation segments from pinning points occurs in the stage at increasing strain and is not fully recovered during the second stage at decreasing strain thus the mean link length increases in a MS test cycle. The onset of thermal activated dislocation cross-slip at about 150 °C favors the dislocation breakaway and consequently enhances the effect on damping.
