Abstract
Crystallization of the metallic glass Fe80B12Si8 has been studied by differential scanning calorimetry, X-ray diffraction and transmission electron microscopy. Samples were annealed isothermally for 15 to 1400 min between 633 and 753 K. The crystalline phases observed are α(Fe, Si) and Fe3B in sequence, with dendritic and cylindrical morphology, respectively. The distribution of α(Fe, Si) particles is rather uniform in the bulk but very non-uniform near both surfaces. The growth of these particles obeys a t 1/2 law and is diffusion controlled.
