退火工艺对Fe-Si-Ni-Al-Ti磁粉芯性能的影响蔡一湘;毛新华;刘辛;谢焕文【摘要】采用气雾化技术并结合模压成形方法制备Fe-3Si-2Ni-0.5Al-2Ti磁粉芯，通过热分析仪、X射线衍射仪、电子探针以及软磁交流测量装置表征和分析了绝缘包覆剂的热稳定性、磁粉芯的相组成、碳氧含量及磁性能，并探讨退火温度、升温速率、保温时间对磁粉芯性能的影响。
结果表明：随退火温度由180℃升高至280℃，磁粉芯的矫顽力下降，磁导率增大，损耗降低；但进一步升高至380℃时，磁粉芯性能下降。
升温速率过快(3℃/min)或过慢(1℃/min)，均不利于磁粉芯性能的提高，较佳升温速率为2℃/min。
当保温时间由60 min延长至90 min时，磁粉芯的矫顽力下降、有效磁导率增大、损耗降低；但进一步延长保温时间(150 min)对磁粉芯性能的改善并不明显。
%Fe-3Si-2Ni-0.5Al-2Ti magnetic powder cores were prepared by gas atomization and compression molding. The thermal stability of insulation binder, phase composition, carbon and oxygen content, magnetic properties of magnetic powder cores were analyzed by thermal analyzer, X-ray diffractometer, electron probe microanalyzer, and soft magnetic alternating current measurement, respectively. The effects of annealing temperature, heating rate, and holding time on the magnetic properties of magnetic powder cores were investigated. The results show that when the annealing temperature increases from 180 to 280℃, the coercivity decreases, effective magnetic permeability increases and loss decreases. However, further increment of the temperature deteriorates magnetic properties of the magnetic powder cores. The fast heating rate (3℃/min) or the slow one (1℃/min) aredetrimental to improve the magnetic properties of cores, the optimal one is 2℃/min. w hen the holding time prolongs from 60 to 90 min, the coercivity decreases, effective magnetic permeability increases and the loss decreases. But further increment of the holding time can’t improve magnetic properties of the cores obviously.【期刊名称】《粉末冶金材料科学与工程》【年(卷),期】2015(000)002【总页数】7页(P218-224)【关键词】Fe-Si-Ni-Al-Ti;磁粉芯;退火处理【作者】蔡一湘;毛新华;刘辛;谢焕文【作者单位】广东省工业技术研究院粉末冶金研究所，广东广州 510650;广东省工业技术研究院粉末冶金研究所，广东广州 510650;广东省工业技术研究院粉末冶金研究所，广东广州 510650;广东省工业技术研究院粉末冶金研究所，广东广州 510650【正文语种】中文【中图分类】TF125.13磁粉芯是1种由软磁金属或合金粉末经绝缘包覆后，采用传统粉末冶金方法制备的1种新型软磁复合材料，它具有饱和磁感应强度高、频率特性良好、恒导磁等特点[1−2]。

非晶软磁材料的退火处理Amorphous soft magnetic materials are widely used in various applications such as transformers, inductors, and magnetic shielding due to their excellent magnetic properties. 非晶软磁材料因其优秀的磁性能，在变压器、电感器和磁屏蔽等各种应用中被广泛使用。
However, the properties of these materials can be enhanced through annealing processes. 但是，通过退火处理，这些材料的性能可以得到提升。
Annealing involves heating the material to a specific temperature and then allowing it to cool slowly in order to relieve internal stresses and soften the material. 退火涉及将材料加热到特定温度，然后让它慢慢冷却，以释放内部应力并软化材料。
One of the key benefits of annealing amorphous soft magnetic materials is the reduction of power loss. 通过退火非晶软磁材料的一个关键好处是减少功率损耗。
During the annealing process, the magnetic domains in the material become more aligned, leading to a reduction in eddy current losses and hysteresis losses. 在退火过程中，材料中的磁畴更加排列整齐，从而减少涡流损耗和磁滞损耗。

The ma-cro-strain, microstructure and magnetic properties of the ribbons annealed at different tempera-tures were observed. Comparing and analyzing the experimental results of low temperature an-nealed samples and high temperature annealed samples, it is found that the microstructure and magnetic properties of the samples annealed at low temperature are different from those of the samples annealed at high temperature. The samples annealed at low temperature are almost still amorphous, while the samples annealed at high temperature are nanocrystalline ribbons. The macro-strain, maximum impedance ratio, magnetic anisotropy and optimum driving frequency of the samples after low temperature annealing have a certain linear relationship with the annealing temperature. The results of this paper have important reference value for improving the soft magnetic properties of Fe-based amorphous alloys by stress annealing in industrial production.KeywordsStress Annealing, Macro-Strain, Microstructure, Giant Magneto-Impedance, Magnetic Anisotropy退火温度对Fe基非晶薄带磁性能的影响许校嘉1，陆轩昂1，方峥2，郭春羽1，范晓珍1，何兴伟1，方允樟1,3*，杨晓红41浙江师范大学物理与电子信息工程学院，浙江金华2浙江旅游职业学院，浙江杭州*通讯作者。
