## Description

- description: Elucidating the individual effects of high- and low-temperature relaxations
    on the internal structure and material properties is a fascinating theme in the
    field of metallic glasses because it can lay the foundation for an advanced glass-property
    tuning scheme through the control of different types of relaxations. In this study,
    several glass models were constructed using melt-quenching (MQ) processes, in
    which high- and low-temperature relaxations were controlled by their cooling rates.
    We found unusual energy–structure–property relationships; even when the glass
    alloys had equivalent potential energies (or free volumes), they exhibited different
    local-order development, elastic stiffness, and plastic deformation properties,
    which depended on the thermal histories in the glass-forming MQ process. The local-order
    development was primarily affected by the high-temperature relaxation occurring
    at approximately the glass transition temperature. Meanwhile, the plastic deformation
    behavior of the metallic glasses was significantly affected by both low- and high-temperature
    relaxations. We also found an interesting relaxation memory effect in the glass
    alloys constructed by the present MQ processes; the glass alloys exhibited an
    atomic-scale dynamic that was affected by the temperature-dependent relaxation
    memories (i.e., high and- low-temperature relaxation memories) of previous MQ
    processes. These results provide new insights into the relaxation physics of glass-forming
    liquids and imply the possibility of an advanced tuning scheme for metallic glasses.
