MOSSBAUER STUDY OF AL13FE4

Results of a Mossbauer study of Al13Fe4 alloy, obtained by rapid solidification of the melt and subsequent annealing for crystallization are presented. The Mossbauer spectrum has been analysed on the basis of the structure of Al13Fe4, as determined from an earlier reported X-ray diffraction study. Accordingly, the spectrum has been fitted to two doublets and a Lorentzian representing grossly two types of Fe sites with different local atomic environments in Al13Fe4 and Fe solid solution in Al respectively. The area fractions of the two doublets are in agreement with the relative abundances of the two types of sites in Al13Fe4. These results should be helpful in understanding local atomic environments in a related quasicrystalline phase of Al-Fe alloy.
