摘要： 在铁基非晶纳米晶合金,普通氮气热处理最佳退火温度的基础上,将热等静压工艺引入到非晶带材磁芯的退火工艺中,探究热等静压工艺对Fe基非晶纳米晶合金软磁性能的影响。用X射线衍射仪、精密磁性元件测试仪和软磁交流设备测量了铁基非晶带材的晶体结构、磁芯的电感L和磁损耗P_s等。结果表明,在频率100 kHz和工作磁感应强度B_m＝0.1 T时,普通氮气保护退火样品的矫顽力和磁损耗为2.04 A/m、10.10 W/kg,而热等静压样品则为1.33 A/m、6.58 W/kg,分别降低了53.4%、34.9%;普通氮气保护退火样品的有效磁导率和品质因数为11 579、0.46,而热等静压则为15 980、0.70,分别增加了38.0%、52.2%。

Abstract: Effect of hot isostatic pressing (HIP) process on soft magnetic properties of Fe-based amorphous/nanocrystalline alloys was investigated by introducing HIP into the annealing process of amorphous strip cores on the basis of the optimum annealing temperature for heat treatment at high-purity nitrogen atmosphere. The crystal structure, core inductance L and magnetic loss P_s of Fe-based amorphous strip were measured by X-ray diffractometer, precision magnetic component tester and soft magnetic AC equipment. The results show that at a high frequency of 100 kHz and working magnetic flax density B_m=0.1 T, the coercivity and magnetic loss of the nitrogen-protected annealed specimens are 2.04 A/m and 10.10 W/kg, while the hot isostatic pressed specimen are 1.33 A/m and 6.58 W/kg, which reduced by 53.4% and 34.9%, respectively. The effective permeability and quality factor of the nitrogen-protected annealed specimen are 11 579 and 0.46, while the hot isostatic pressed specimen are 15 980 and 0.70, which increased by 38.0% and 52.2%, respectively.
