## Description

- description: The effect of p-block elements (Ga, Ge and In) addition on grain boundary
    structures and room temperature mechanical responses was investigated on extruded
    Mg binary alloys with fine-grained structures.  Grain boundary segregation was
    confirmed in the Mg-Ga and Mg-In alloys, whereas the Mg-Ge alloy did not show
    such microstructures associated with solubility.  Grain boundary segregation affected
    the plastic deformation of the Mg-Ga and Mg-In alloys.  In particular, the Mg-In
    alloy had a large strain rate dependency and exhibited good deformability at low
    strain rate regimens.  First-principles calculations indicated that p-block elements
    produce a bond-weakening effect at grain boundaries, and atomistic distances at
    grain boundaries varies according to each element.  Solute atom which brings about
    both bond-weakening and bond-expansion effects to Mg atoms is effective in enhancing
    the contribution of grain boundary sliding in deformation.
