摘要

采用Ｍ　ｓｓｂａｕｅｒ效应和ＸＲＤ分析方法研究了非晶合金Ｆｅ７３．１Ｃｕ３．２Ｎｂ３．２Ｓｉ１２．５Ｂ１０．０的晶化。实验表明，该非晶合金有两个晶化阶段。在第一阶段晶化后，样品主要由ＤＯ３型的ａ—ＦｅＳｉ合金的超细颗粒和作为晶界的非晶相两部分组成。随着退火温度的上升，晶化相的含量增加，非晶相含量减少、在第二阶段晶化后，残余的非晶相就晶化为Ｆｅ２Ｂ和Ｆｅ２３Ｂ６化合物以及可能为Ｆｅ－Ｎｂ－Ｂ之类的顺磁相。

Abstract

Crystallization of the amorphous Fe73.1Cu1.2Nb3.2Si12.5B10.0 alloy has been investigated by M6ssbauer spectyoscopy and X-ray diffraction. The experimental results show that there exist two crystallization steps in this alloy. After the first step the sample consists mainly of two part

i.e. ultrafine crystal particles of DO3 type a-FeSi alloy and an amorphous phase as grain boundaries. With increasing annealing temperature

amount of the crystal phase increases with the expense of residual amorphous phase. Residual amorphous Phase changes to Fe2B and Fe23B6 compound as well as presumed Fe-Nb-B paramagnetic phase after the second step.
