Amorphous Pd100−x−ySixFey alloys with the composition of x=15, 17.5, 20 and y=0, 0.3, 1 in at% were investigated. Quadrupole splitting decreases with the increase of silicon content and its extrapolated value almost coincides with that of crystalline Pd3Si(Fe). The result represents the similarity of local atomic configuration of the both structures. Isomer shift of the amorphous alloys is in the range of 0.08∼0.13 mm/s and increases with silicon content, while that of c-Pd3Si(Fe) is a negative value of −0.11 mm/s. The results are explained by the difference in the shielding effect of 57Fe nucleus in both phases.<BR>The amorphous alloys are stable even after 575 hours ageing at 200°C, and crystallize to Pd3Si above 250°C. Our results are different from those obtained by Masumoto et al. The different ageing behaviors may arise from the difference in the microstructure of the examined amorphous materials.
