| 中文摘要 | Effect of static stress on magnetomechanical damping of Fe-15Cr and Fe-8Al (wt.%) alloys has been investigated by using dynamic mechanical analyzer (DMA) with three-point bending model. The temperature sweeping is used to measure the damping capacity and the variation of damping capacity with strain amplitude under different static stresses is deduced through a matrix method. The result shows that three-point bending model is capable for measuring magnetomechanical damping capacity with reliable results. Under no static stress condition, the deduced damping curve is fitted well with Smith and Birchak (S-B) model at low strain amplitude. However, the deduced damping capacity is higher than the value predicted by S-B model at high strain amplitude. With increasing static stress, the deduced damping capacity decreases significantly and becomes strain amplitude-independent. Compared with S-B model, the deduced damping capacity under applied stress is obviously higher which can be associated with the dislocation damping generated by unpinning dislocations as the static stress increases.
