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.

• 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。
