综述了非晶磁性合金材料性能与近年来发展的应用之间的关系。在电力领域，当现代电力电子设备、变速电机等非线性负载日益增多，配电系统中谐波较高时，非晶金属基变压器在降低变压器损耗方面具有重要作用。在这些局部功率调节装置中，非晶金属的多功能性使得实现不同性能的电感成为可能，这些电感可用作电扼流圈、储能电感、饱和磁芯等。其中一些磁芯用于电信系统，例如DSL中的数字网络接口变压器和带通滤波器。在控制和传感领域，包括电子物品监视标记在内的机械/电气/磁传感器越来越多地利用非晶合金的快速通量反转/低磁损耗特性。本文还介绍了近年来非晶金属块体磁体领域的研究进展。
A review is given on the relationships between the material properties and the recently-developed applications of amorphous magnetic alloys. In the electrical power area, amorphous metal-based transformers are found to have considerable impact in reducing transformer losses when the power distribution systems contain higher harmonics generated by an ever-increasing number of nonlinear loads such as modern power electronic devices, variable-speed motors, etc. In these local power conditioning devices, the versatility of amorphous metals makes it possible to realize inductors with varying performances which are used as electrical chokes, energy storage inductors, saturable cores, etc. Some of these magnetic cores find use in telecommunication systems, examples of which include digital network interface transformers and bandpass filters in DSL. In control and sensing areas, mechanical/electrical/magnetic sensors including electronic article surveillance markers are increasingly utilizing the fast flux-reversal/low magnetic-loss nature of amorphous alloys. Recent advances made in the area of amorphous metal-based bulk magnets are also mentioned.
