摘　　要：Fe_(20)Al_(80)非晶态粉末是通过180球磨而制备的。X射线衍射和透射电子显微镜实验不但证实它的非晶性,而且给出它的平均颗粒度大小和晶化产物。穆斯堡尔谱测量确定了该非晶态粉末的顺磁性和晶化度。Fe20Al80 amorphous powders were prepared by ball milling through 180 hours. X-ray diffraction and transmission electron microscope experiments indicate the powder sample is amorphous and also show the average particle size and crystallization products. The paramagne-tism and crystallinity of amorphous material are determined by Mossbauer effect measurements.
