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。
The nanocrystalline Fe_ (76.5-x) Cu_ (1.0) Nb_xSi_ (13.5) B_ (9.0) (X = 1, 3, 5 and 7) nanocrystalline alloys prepared by the amorphous method were investigated by Mossbauer spectroscopy In the interface amorphous phase microstructure. The magnetic ordering temperature Tc of the residual amorphous phase was measured using a Mossbauer scanning technique. The effect of nanocrystalline grains on the interface amorphous phase by magnetic interaction and the effect of Nb on the alloy were analyzed.
