机械合金化Fe-B合金的Mssbauer谱研究

MoSSBAUER STUDY OF THE MECHANICAL ALLOYING Fe-B ALLOY

用Mossbauer谱分析方法研究了配料原子比为Fe_(70)B_(30),Fe_(55)B_(45)和Fe_(30)B_(70)各样品经机械合金化所形成的合金相的结构特点及其非晶相在退火过程中的转变。揭示出此类非晶相与相应的Fe-B化合物之间存在一定程度的联系。

Using Mossbauer spectroscopy, We have studied the structural characteristics of the alloy phases of three samples formed by the process of mechanical alloying. The starting compositions of these samples are Fe70B30, Fe55B45 and Fe30B70. The crystallization or transition of the amorphous phases under annealing has also been examined. It was found that a certain relation exist between the amorphous phases and corresponding Fe-B compounds.
