Abstract
The damping properties of Fe-Cr and Fe-Cr based alloys have been investigated by the cantilever method and the resonant bar method. The change in damping capacity is studied as a function of several parameters including temperature, magnetic field, cold work and heat treatment. The results are correlated with measurements of the coercive force. Binary Fe-Cr alloys with 12-14 % Cr exhibited damping capacities as high as 80 % when heat treated at 1200 °C while the alloy Fe-12Cr-3Al already exhibited damping capacities of the order of 40-60 % when heat treated at temperatures above 750 °C.
