Abstract

Synchrotron high-energy X-ray diffraction has been used to determine the atomic structural details in three selected melt-spun Al-based metallic glasses with different glass-forming abilities (GFAs), Al₈₆Ni ₇Y_4.5Co₁La_1.5, Al ₈₆Ni₆Y₆Co₂ and Al ₈₄Ni₉Y₇. The atomic pair species, pair fractions and their corresponding bond distances have been established for each metallic glass. These results address the GFA of Al-based metallic glasses from the topological perspective, and explain the structural origins that are responsible for the excellent GFA of Al₈₆Ni₇Y _4.5Co₁La_1.5.
