AbstractThe atomic packing structure of Al90.5Y9.5, Al89.5Fe4.5Y6, Al85.5Ni9.5Y5, Al89Co5.5Y5.5 and Al85.5Co9.5Y5 metallic glasses (MGs) was studied using the extended X-ray absorption fine structure (EXAFS) technique, and the atomic packing efficiency (APE) of solute-centered clusters was calculated. The results indicated that both Co- and Y-centered clusters possess higher APE in Al89Co5.5Y5.5 MG than in Al85.5Co9.5Y5 MG, due to which the former has the best glass-forming ability (GFA) in Al-Co-Y system. The chemical property of transition metals (TMs) influences the medium range ordering, i.e. the connection of solute-centered clusters. As TM element changes from Fe, Co to Ni, the TM-centered clusters tend to share more and more Al atoms, resulting in the sequential increase of the concentration ratio of TM/Y in Al89.5Fe4.5Y6, Al89Co5.5Y5.5 and Al85.5Ni9.5Y5 MGs that have the best GFA in their respective alloy system.
