Abstract

This study examined the structural factors that determine the properties of amorphous alloys. The properties of amorphous alloys were found to be intimately related to the atomic packing density, characterized by short-range ordered (SRO) atomic clusters and free volume. With increasing packing density, the modulus and strength increased, while the plasticity decreased. We discuss the fundamental microstructural aspects that influence several representative properties of amorphous alloys in terms of the packing state characterized by fractions of SRO atomic clusters.
