研究了５２０℃下等温退火Ｆｅ_（７３．５）Ｃｕ_（１．０）Ｍｏ_（３．０）Ｓｉ_（１３．５）Ｂ_（９．０）纳米软磁合金的磁性，发现当退火时间ｔａ为４０ｍｉｎ时，合金的起始磁导率μｉ最高，约为５×１０~４，探讨了磁性的影响因素。
The magnetic properties of isothermally annealed Fe_ (73.5) Cu_ (1.0) Mo_ (3.0) Si_ (13.5) B_ (9.0) nanocrystalline soft magnetic alloys at 520 ℃ were investigated. It is found that when the annealing time ta is 40min, the initial permeability of the alloy μi the highest, about 5 × 10 ~ 4, discussed the impact of magnetic factors.
