Analysis of the atomic structure of metallic glass of composition Al87Ni10Nd3 with the use of a fragmentary model

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.
