报道了新开发的纳米晶Ｆｅ７３．５Ｃｕ１Ｎｂ２Ｖ１Ｓｉ１３．５Ｂ９合金的综合软磁性能。新合金的高频铁损水平为：Ｐ３／１００ｋ＝５１０ｋＷ·ｍ－３，Ｐ２／２００ｋ＝７４８ｋＷ·ｍ－３，Ｐ２／５００ｋ＝３６７１ｋＷ·ｍ－３和Ｐ０．５／１０００ｋ＝８７１ｋＷ·ｍ－３。新合金的铁损比早期开发的纳米晶Ｆｅ－Ｃｕ－Ｎｂ－Ｓｉ－Ｂ合金的低且明显低于优良的功率Ｍｎ－Ｚｎ铁氧体Ｈ７ｃ４的铁损。对铁损与频率和幅值磁通密度的关系进行了分析。也报道了新合金在若干方面的实际应用。
The comprehensive soft magnetic properties of the newly developed nanocrystalline Fe73.5Cu1Nb2V1Si13.5B9 alloy have been reported. The new alloy had high-frequency iron loss levels of P3 / 100k = 510kW · m-3, P2 / 200k = 748kW · m-3, P2 / 500k = 3671kW · m-3 and P0.5 / 1000k = 871kW · m- 3. The new alloy has a lower iron loss than the earlier developed nanocrystalline Fe-Cu-Nb-Si-B alloy and is significantly lower than the iron loss of an excellent power Mn-Zn ferrite H7c4. The relationship between iron loss and frequency and amplitude magnetic flux density was analyzed. Also reported the practical application of new alloys in several aspects.
