Abstract

Use of a fragmentary model in the analysis of the atomic structure of an Al87Ni10Nd3 amorphous metal alloy made it possible to determine that it has fragments of the structures of three phases, namely, Al, Al3Ni, and Al3Nd. After crystallization of the alloy under the action of pulse photon irradiation, polycrystals of pure aluminum and two Al3Ni and Al4Nd intermetallides were found in it. Because fragments of structure Al4Nd were not observed in the amorphous state, it follows that atoms which form fragments structure Al3Nd rearrange to structure Al4Nd upon crystallization.
