摘要

利用XAFS（X射线吸收精细结构）和XRD（X射线衍射）方法研究了机械合金化Fe

0.6

0.4

系统在制备过程中的晶体结构和Fe原子的局域配位环境。结果表明

球磨5h

样品中Fe、Ni原子开始产生合金化

但仍然为bcc和fcc混合的两种物相;球磨10h后

bcc结构Fe的特征配位峰消失

转化为fcc结构

随着球磨时间的增加

配位无序度逐渐增大;球磨40h后

Fe原子的近邻结构又有新的变化

是由多种物态组成的混合物。

Abstract

Structures of the mechanically alloyed Fe0.6Ni0.4 after milling for 5

40 h were investigated by X-ray absorption fine structure （XAFS） and X-ray diffraction （XRD）. The results show that after milling for 5 h the patterns with bcc-like structure of a-Fe and with fee-like structure of Ni were observed. After milling for 10-20h the patterns with bcc-like structure of a-Fe disappeared

and only the patterns with fee-like structure were observed. After milling for 40 h the weak patterns with bcc-like structure appeared again. So the mechanically alloyed Fe0.6Ni0.4 after milling for 40 h is not a homogeneous supersaturated solid solution.
