Influence of plastic deformation and asymmetric loading on the properties of Fe–Al and Mn–Cu damping alloys

Attention focuses on how plastic deformation and asymmetric loading affect the properties of Fe‒Al and Mn–Cu damping alloys. When the vibrational amplitude is small, the damping properties of Fe‒Al alloys are highly sensitive to external static loads; the sensitivity is much less for Mn–Cu alloys. With decrease in the grain size of Fe–Al alloys, the sensitivity to external static loads is much reduced.
