The atomic structure of the amorphous metallic alloy Al83.5Ni9.5Si1.4La5.6 is investigated based on the analysis of the experimental atomic radial distribution function (ARDF) in the fragmentary model. A comparative analysis of the most probable interatomic distances in the alloy and possible compounds based on it has demonstrated the presence of crystalline nuclei of the following phases: Al3La, Al3Ni, Al2.12La0.88, Al3Ni5, and Al. The largest ones (1–2 nm) are nuclei of the Al3Ni and Al compound, while the majority nuclei of all the other phases had sizes of about 7 Å. Al and Al3Ni, as well as Al11La3 and Al5.56LaNi1.44 are observed in the crystallized alloy.
