Abstract
The crystallisation of the metallic glass Y0.66Fe0.34 has been investigated using 57Fe Mossbauer effect spectroscopy, differential scanning calorimetry, X-ray diffraction, and high-temperature resistivity measurements. The emphasis of this work is on the microscopic changes which occur in the local environments of the Fe atoms during the crystallisation process. The crystallisation of this glass occurs in two distinct steps associated with the formation of HCP Y and the Laves phase compound YFe2. The activation energies for these two steps were found to be 2.2 eV and 3.6 eV respectively.Keywords
