In this paper, the influence of annealing temperature and other factors on the damping properties of Fe-Cr-Si-Mo, Fe-Cr-Co and Fe-Cr-Al ferromagnetic alloys has been studied.On the basis of the irreversible internal stress theory of magnetic domains, The mechanism of internal friction due to magnetism-mechanical hysteresis was determined.At the same time the other properties of the alloy were determined, the annealing temperature corresponding to the high damping property of the alloy and the service temperature range of the alloy were determined.It was beneficial to seek the ferromagnetic alloy with high damping properties Explore
