摘　　要：研究热处理工艺、材料粒度对Fe73.5Cu1Nb3Si13.5B9材料微波电磁性能的影响,对该类材料的微波电磁性能和吸波性能进行测试。结果表明:热处理工艺对材料的微波电磁性能产生较大的影响,达到晶化条件的热处理工艺有利于提高材料的电磁性能;随着材料粒度的减小,微波电磁性能提高,电磁参数之间的匹配性提高;Ⅴ级粒度材料的最低反射率达到-12 dB,低于-5 dB的频宽达12.5 GHz。The effect of heat treatment process and particle size on microwave electromagnetic properties of Fe_3.57Cu_1Nb_3Si_13.5B_9B9 was studied. The absorbing properties of such materials were also tested. The results show that the heat treatment for crystallization conditions will help improve the microwave electromagnetic properties of materials. The microwave electromagnetic properties and the electromagnetic matching parameters increase with the material particle size decreasing. The minimum reflectivity of materials reaches -12 dB, while the frequency width lower than -5 dB reaches 12.5 GHz for V class powder.
