利用非晶晶化法制备了(Fe0.99Cu0.01)78Si9B13纳米晶合金。发现其显微硬度Hv与晶粒尺寸d之间基本服从Hall-Petch关系。利用M?ssbauer谱研究了晶粒尺寸为30nm的材料中类金属原子的分布及其对晶化相电子结构的影响。By using the crystallization method, nanocrystalline (Fe0.99Cu0.01)78Si9B13 alloys were synthesized. The relationship between microhardness Hv and grain size d was proved to obey Hall-Petch relation. By means of M?ssbauer spectroscopy, the distribution of metalloids Si and B and their influence on electronic structure of crystallized phases were also investigated.
