摘　　要：采用穆斯堡尔谱学方法,研究采用非晶晶化法制备的Fe_(76.5-x)Cu_(1.0)Nb_xSi_(13.5)B_(9.0)(X=1,3,5和7)纳米晶合金中界面非晶相的显微结构。采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。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元素在该系列合金中所起的作用。Using the method of Mossbauer spectrscopy, we research on the microstructure of amorphous phase on the interface for Fe76.5-xCu1.0NbxSi13.5B9.0(x = 1,3,5 and 7)nanocrystalline alloy prepared by means of amorphous crystallization. We utilize the thermal scanning technique of Mossbauer to determine magnetic ordered temperature of the residual amorphous phase, analyze the influence of magnetic interaction between nanocrystalline grain on amorphous phase on the interface and the role played by the element of Nb in the series of these alloys.
