把不同温度退火后非晶态Fe76.6Si4.9B18.5粉末的穆斯堡尔谱与未退火时的谱及制备粉末用原料的谱进行对比，发现随退火温度的提高，粉末颗粒的平均内场有些增大，α-Fe晶相也少许增加，即出现偏析现象.在晶化温度以上退火时，非晶态结构转变为晶态结构，而且α-Fe偏析明显增多，与制备粉末用的合金原料晶态相的各相比例明显不同.这些性质类似于非晶态FeSiB合金薄带样品.

The mossbauer spectrum of Fe76.6Si4.9B18.5 powders are measured for the samples of annealing at different temperature,not annealing and the alloy resulted in the powders.The average hypefine field is increased a little and α-Fe crystals grow and increased slowly when annealing temperature is raised.Amorphous structure is changed into crystalline and the ratio of crystallize phases are obviously different from the alloy.The properties of the powders are similar to the amorphous FeSiB ribbon.
