A melt-spun metallic Fe80B20 glass was subjected to high-energy ball milling. Microstructural changes of the glassy sample during milling were characterized by means of x-ray diffraction, differential scanning calorimetry, Mossbauer spectroscopy, and Curie temperature measurements. It was found that the metallic glass may relax towards a low energetic configuration by mechanical milling, leading to a reduction of the heat release associated with crystallization of the amorphous phase and an increase of the average hyperfine field as well as of the Curie temperature. These results can be attributed to the occurrence of a strong short-range order in the amorphous state. Our experimental observations suggest that mechanical milling may induce structural relaxation in the amorphous Fe80B20 alloy. © 1996 American Institute of Physics.
