Atomic Structure of the Amorphous Metallic Alloy Al83.5Ni9.5Si1.4La5.6
Source abstract
Abstract
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.
