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 M?ssbauer effect measurements.
