测量制备态和退火态的Fe76.5-xCu1NbxSi13.5B9(X=0、10、30、5.2、7.2)合金Mossbauer谱结果表明晶化后Nb、B等元素向晶界区扩散,在残余非晶中形成了富Nb、B区和贫Nb、B区Nb抑制非晶相的晶化和FC2B相的析出,并对磁织构有一定影响

The Mossbauer spectra were measured for amorphous Fe76. 5-x. Cu1 Nb.Si13. 5 B9 (x=0.0、1. 0、3.0、 5.2、7.2) alloys both at as-cast and annealed state, in order to investigate the influence of Nb on the formation of nanocrystalline alloy. The results indicate
