主要采用穆斯堡尔谱学方法，研究了非晶晶化法制备的Ｆｅ７６．５－ｘＣｕ１．０ＮｂｘＳｉ１３．５Ｂ９．０（ｘ＝１，３，５和７）纳米晶合金中界面非晶相的显微结构。用穆斯堡尔热扫描技术测定了残余非晶相的磁有序温度Ｔｃ。观察到非晶合金的晶化温度，磁有序温度和平均磁超精细场有规律性的变化。分析了纳米晶粒通过磁相互作用对界面非晶相的影响以及Ｎｂ在该系列合金中所起的作用。 Mainly using Mossbauer spectroscopy method to study the amorphous amorphous phase prepared Fe76.5-xCu1.0NbxSi13.5B9.0 (x = 1,3,5 and 7) nanocrystalline alloy interface amorphous phase Microstructure. The magnetic ordering temperature, Tc, of the residual amorphous phase was determined using a Mossbauer scanning technique. Crystallization temperature, magnetic ordering temperature and average magnetic hyperfine field of amorphous alloys were observed to have regular changes. The effect of nanocrystalline grains on the amorphous phase of the interface by magnetic interaction and the role played by Nb in this series of alloys were analyzed.
