The damping capacities of Fe-13Cr-6Al, Fe-12Cr-1Mo-6Al and Fe-12Cr-1Mn-6Al (at.%) alloys as a function of strain-amplitude tested in a given static load are characterized in the 3-point bending deformation mode. After being modified, Smith-Birchak model is applied to describe the results. It is shown that the modified model agrees with the experimental data much better than the original one. Finally, the in?uences of stress factors on the damping capacity of the alloys are analyzed.
