本文报道Ｆｅ７４．７－ｘＣｕ１ＮｂｘＶ１．８Ｓｉ１３．５Ｂ９（ｘ＝１，１．５，２）纳米晶软磁合金的综合磁性。ｘ＝２的合金的高频铁损水平为：ｐ３／１００ｋ＝４６８ｋｗ／ｍ３：Ｐ２／２００ｋ＝７０６ｋＷ／ｍ３；Ｐ２／５００Ｋ＝３６２０ｋｗ／ｍ３和Ｐ０．５／１０００ｋ＝８１０ｋｗ／ｍ３优于Ｆｅ－Ｃｕ－Ｎｂ－Ｓｉ－Ｂ类纳米晶合金的水平所考察的三种合金铁损水平都大大优于功率优良的Ｍｎ－Ｚｎ铁氧体Ｈ７Ｃ４考察了起始磁化率的温度关系，观察到原始非晶样品出现两个尖锐的Ｈｏｐｋｉｎｓｏｎ峰，与此不同的是，在具有最佳磁性的样品中只出现第二Ｈｏｐｋｉｎｓｏｎ峰，用Ｔｈｏｍａｓ理论解释了这一现象。观察到高温下纳米α－Ｆｅ（Ｓｉ）晶粒系统的超顺磁行为，起始磁化率的温度关系符合Ｃｕｒｌｅ－Ｗｅｉｓｓ定律。
In this paper, the comprehensive magnetic properties of Fe74.7-xCu1NbxV1.8Si13.5B9 (x = 1, 1.5, 2) nanocrystalline soft magnetic alloys are reported. The high-frequency iron loss of the alloy with x = 2 is: p3 / 100k = 468kw / m3: P2 / 200k = 706kW / m3; P2 / 500K = 3620kw / m3 and P0.5 / 1000k = 810kw / Cu-Nb-Si-B nanocrystalline alloy level of the three alloy iron loss levels are much better than the excellent power of Mn-Zn ferrite H7C4 investigated the initial susceptibility of the temperature relationship, the original observed non- In contrast to two sharp Hopkinson peaks in the crystalline sample, the second Hopkinson peak only appears in the sample with the best magnetic properties and is explained by the Thomas theory. The superparamagnetic behavior of the nano-α-Fe (Si) grain system at high temperature was observed. The temperature dependence of the initial susceptibility was in accordance with the Curle-Weiss law.
