本文综述了高磁致伸缩铽镝铁合金的研究进展。这包括讨论域结构，磁化过程，微观结构，样品制备，磁致伸缩，不同的化学成分对合金的磁性能的影响，以及这些材料的可能应用。近年来已经发现，材料性能在增加的应变幅度和样品之间的可变性降低方面都有稳定的改善。这种材料现在被应用于磁致伸缩换能器、致动器和自适应振动控制系统。
This paper reviews recent developments in highly magnetostrictive terbium-dysprosium-iron alloys. This includes discussion of domain structure, the magnetization process, microstructure, sample preparation, magnetostriction, effects of different chemical compositions on magnetic properties of the alloys, and possible applications of these materials. It has been found over recent years that there has been a steady improvement in material properties, both in terms of increased strain amplitude and reduction in variability from sample to sample. The material is now finding applications in magnetostrictive transducers, actuators and adaptive vibration control systems.
