## Description

- description: 'Static annealing process of 423 K for 2.5 hours is enough to segregate
    alloying elements at {10-12} twin boundaries in Mg binary alloys.  These segregated
    twin boundaries play a role in obstruction of dislocation slips; thus, they contribute
    to increase in hardness.  The results obtained from internal friction tests reveal
    that, irrespective of solute elements, induced twin boundaries are effective in
    enhancing damping capacity, owing to twin boundary reversible motion, i.e., growth
    and shrinkage.  In contrast, in comparison of the loss factor of specimen with/without
    twin boundary segregation, segregation leads to a decrease in damping capacity.  The
    solute element also affects the difference in damping properties with/without
    twin boundary segregation.  The energy barrier required to occur twin boundary
    sliding for each solute atom is computed to consider energetical kinetic using
    first-principles calculations.  Energy barrier that is influenced by solute atom
    is closely related to loss factor.  When solute element having a characteristic
    of high (or low) energy barrier exists at twin boundaries, such an alloying element
    prevents (or enhances) the occurrence of twin boundary motion.  As a result, the
    binary alloy shows low (or high) loss factor, respectively, in damping tests.  '
