利用非晶晶化法制备了(Fe_(0.99)Cu_(0.01)_(78)Si_9B_(13)纳米晶合金。发现其显微硬度H_v与晶粒尺寸d之间基本服从Hall-Petch关系。利用Mossbauer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。
The (Fe_ (0.99) Cu_ (0.01) _ (78) Si_9B_ (13) nanocrystalline alloys were prepared by the amorphous method and found to have a Hall-Petch relationship between the microhardness H_v and the grain size d The Mossbauer spectrum studies the distribution of metalloid atoms in the material with a grain size of 30 nm and its effect on the electronic structure of the crystallized phase.
