Cu、Mo、Ti have no effect on the phase structure of Fe-13Cr-2Al-1Si damping alloy. “Dendritic” magnetic domain structures can be easily observed in the alloys. The alloys can keep high damping behavior in a wider range of strain amplitude. Damping behavior of alloy is somewhat different from that of traditional ferromagnetic alloy. In the high strain amplitude area there is ferromagnetic damping.
