用MA方法研究添加Si、Fe元素对77Fe21B2Si合金结构的影响

The Investigation into the of Si、 Fe Additions on 77Fe_(21)B_2Si Alloy Structure by MA Method

利用高能球磨机研究了添加Si、Fe元素对77Fe21B2Si合金在球磨过程中的结构变化。作者用结构组态曲线非常明显的反映了随球磨时间增加各组态的变化。实验证明Si元素很容易与其它元素合金化,同时Si又在固态反应非晶化中起着重要作用,而Fe只是提供基础结构。

The effect of Si、Fe additional element on structural change of 77Fe21B2Si alloy during the course of ball milling by using high energy ball mill is studied in present work.We make use of structural Configuration cu rve to reflect obviously the change of respective configuration with time increase of ball milling.Experiments prove that the element Si is very easy eo be alloyed with other elements,and also plays an important role in amo-rphism of Solid-State reaction,but element Fe ouly Provides base structure.
