摘要： The damping capacities of Fe-13Cr-6Al, Fe-12Cr-1Mo-6Al and Fe-12Cr-1Mn-6Al (at.%) alloy 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 shows that the modified model agrees with the experimental data much better than the original one. Finally, the influences of stress factors to damping capacity of the alloys are analyzed.
