The crystallization process of the Fe91Zr9 amorphous alloy has been followed by means of two experimental techniques, EXAFS and Mössbauer spectroscopy. X-ray absorption spectra on Fe K-edge and Mössbauer spectra of six samples with different degrees of crystallization have been measured at room temperature in order to obtain information about the structural changes that take place. From the beginning of the crystallization process it is clearly seen that a crystalline phase with a bcc-type structure appears. From the obtained data we can conclude that this phase is nearly pure bcc-Fe, with small amount of impurities in its structure.
