利用Ｍｓｓｂａｕｅｒ谱，同步辐射小角Ｘ射线散射和大角Ｘ射线衍射等实验技术对非晶态Ｆｅ（７３．５）Ｃｕ１Ｎｂ３Ｓｉ（１３．５）Ｂ９合金的结构弛豫行为进行了研究。结果表明：晶化前退火引起原子结构，磁畴结构，电子密度的一系列变化；自由体积不断减少，沿条带平面内的宽畴成分增加，表面优先晶化；晶化前在４００℃时形成了Ｃｕ的团簇结构，并引入了很大的电子密度不均匀性。
The structure relaxation behavior of amorphous Fe (73.5) Cu1Nb3Si (13.5) B9 alloy was investigated by Mssbauer spectroscopy, synchrotron radiation X-ray scattering and high angle X-ray diffraction. The results show that the pre-crystallization annealing leads to a series of changes in the atomic structure, magnetic domain structure and electron density; the free volume decreases continuously, the wide-domain composition increases along the plane of the strip and preferentially crystallizes on the surface; The Cu cluster structure was formed and introduced a great deal of electron density inhomogeneity.
