采用适当的热处理工艺将相同成分的Fe_(78)B_(13)Si_9非晶态合金条带晶化制备成纳米晶合金;测定并研究了纳米晶合金的微观结构(晶体结构及尺寸)和一些结构敏感性能(热膨胀、比热),同时,将其与同样成分的非晶态、大晶粒状态合金的性能进行比较分析,认为由于纳米晶合金特殊的微观结构(短程无序),使其在性能上表现出与通常材料有很大差异。

A new method was developed for preparing nanocrystalline alloy made of the identi- cal compositional Fe_(78)B_(13)Si_9 amorphous ribbon by suitable isothermal annealing.Its microstructure and some structure-sensitive properties.including thermal expansion,spe- cific heat,etc.,have been studied and measured.Comparative analysis of properties was also carried out with amorphous and coarse-grained crystalline alloys of same composi- tion,thus.it is believed that so novel differences in properties from usual materials would be made by the particular microstructure of short range disorder of the nanocrystalline alloy.
