| Abstract: | The damping mechanisms of ferromagnetic alloys are presented systematically in this paper, particularly on the characteristics and impact factors of the magnetomechanical hysteresis damping originating from the stress-induced irreversible movement of magnetic domain walls. The chemical composites and heat treatment can also affect the damping capacity, which depends primarily on the magnetic parameters, microstructures and internal stress in the alloys. |
