从Ｈｏｐｋｉｎｓｏｎ效应及Ｘ光衍射技术研究了Ｆｅ（７３．５）Ｃｕ（１．０）Ｎｂ（３．０）Ｓｉ（１３．５）Ｂ９纳米软磁合金的居里温度特性。随晶化退火温度Ｔａ的提高，合金中αＦｅ－Ｓｉ纳米晶相的居里温度提高，但低于相同Ｓｉ含量下的常规Ｆｅ－Ｓｉ合金，且与显微组织结构有关，当Ｔａ较低时，合金中非晶相的居里温度与原始非晶合金基本相同。但其Ｈｏｐｅｉｎｓｏｎ峰宽化，Ｔａ＞７８３Ｋ后，其Ｈｏｐｋｉｎｓｏｎ４消失，无法判断居里温度。认为居里温度的上述特性与合金晶粒的小尺寸特性及元素成分分布特性有关。
The Curie temperature characteristics of Fe (73.5) Cu (1.0) Nb (3.0) Si (13.5) B9 nano-soft magnetic alloys were investigated by Hopkinson effect and X-ray diffraction. With the increase of crystallization annealing temperature Ta, the Curie temperature of the αFe-Si nanocrystalline phase in the alloy increases, but it is lower than that of the conventional Fe-Si alloy with the same Si content, and is related to the microstructure. When Ta is low , The Curie temperature of the amorphous phase in the alloy is basically the same as that of the original amorphous alloy. However, its Hopeinson peak is broadened. After Ta> 783K, its Hopkinson4 disappears and the Curie temperature can not be judged. The above characteristics of the Curie temperature are believed to be related to the small size characteristics of the alloy grains and the distribution of the elemental composition.
