Abstract
The main kinetics parameters of the crystallization of Fe80SixB20-x (w ith x = 2, 4, 6, 8, 10) and Fe75Si15B10 glassy ribbons have been deter mined using differential scanning calorimetry measurements. The struct ure of the materials at various stages has been observed using transmi ssion electron microscopy, electron and X-ray diffraction analysis. Th e crystallization process in this system is found to consist of two di stinct steps: individual steps represent complex processes from a stru ctural point of view. The mechanism of crystallization is described in terms of a local ordering (cluster) model, based on the role of the S i atoms. (C) 1997 Elsevier Science S.A.
