| 摘 要： | 用Ｘ射线衍射技术和穆斯堡尔谱技术，研究了Ｆｅ７３．５ＣｕＭｏ３Ｓｉ１３．５Ｂ９合金的结构和超业细相互作用。该合金的相组成为α－Ｆｅ（Ｓｉ）纳米晶和边界相即五余非晶相。典型纳米晶状态下的穆斯堡尔谱由５条亚谱构成，其中４条亚谱为６峰谱，对应α－Ｆｅ（Ｓｉ）相中的４种不同环境的Ｆｅ原子。另１条亚谱对应边界处的非晶相，研究了非晶带材经５００－６００℃不同温度晶化处理后的穆斯堡尔谱特性。

| Abstract: | Microstructure and superfine interactions of Fe CuMo Si B nanocrystalline alloy (Mo alloy) produced by annealing the rapidly quenched alloy have been investigated using X - ray diffraction and Mossbauer spectroscopy. The pbase oonstituent of the Mo al- loy is a -Fe (Si) nanocrystalline phase with DO3 structure and boundary phase (residual amorphous phase) . Mossbauer spectra of typical nanocrystalline phase of the alloy consists five sextets subspectras , four subspectras are corresponded with four kinds of different environznents of Fe atoms in nanocrystalline grain pbase a - Fe(Si) and the last is bounda- ry phase(residual amorphous phase). The properties of Mossbauer spectra of the alloy rib- bons annealed at 500C and 600 C have been investigated. |
