利用悬臂梁装置对Fe-16 Cr-2.5Mo阻尼合金的阻尼性能进行了研究。利用改进的迈克尔逊干涉仪测量了薄膜的磁致伸缩特性。使用磁流体的域形态进行光学观察。通过分析合金的磁致伸缩性能与退火工艺的关系，讨论了合金的磁机械滞后效应。结果表明，退火样品的饱和磁致伸缩系数与阻尼性能的变化规律基本一致。由于退火态合金中存在广泛的局部内应力，随着退火温度的升高和退火时间的延长，磁畴的迁移率和结构都发生了变化。局域内应力不仅钉扎了电畴的迁移率，而且使电畴结构无序化。在900 °C退火1h的样品中，磁畴尺寸和90°磁畴的数量是导致最高阻尼性能的主要原因。但随着退火时间的延长，90°畴数量急剧减少，合金中出现更多的非均匀畴。尖峰结构域也可以钉扎结构域壁。
The damping capacity of Fe–16Cr–2.5Mo damping alloy was analyzed using a cantilever device. The magnetostriction property was measured using an improved Michelson interferometer. The domain morphology was optically observed using a magneto-fluid. Magnetomechanical Hysteresis Effect (MMHE) was discussed by analyzing the relationship between the magnetostriction performance and the annealing process of the alloy. The results show that the variation of saturate magnetostriction coefficient is quite consistent with that of the damping capacity of the annealed samples. With the local internal stress widely distributing in the annealed alloy, both the domain’s mobility and their structure vary with the increasing annealing temperature and time. The local internal stress not only pins the domain mobility but also makes the domain structure disorder. The domain size and the number of 90° magnetic domains are responsible for the highest damping capacity of the sample annealed at 900 °C for 1 h. However, with the prolonged annealing time, the number of 90° domain decreases sharply and more heterogeneous domains appears in the alloy. The spike domains can also pin domain-walls.
