## Description

- description: " Shaping of dense ceramics is difficult due to their inherent brittleness.
    Nanograined ceramics like tetragonal zirconia (TZP) can be superplastically deformed
    and shaped at high temperatures owing to grain boundary sliding (GBS). Herein,
    the enhanced plasticity of gadolinium-doped ceria (GDC) ceramics under mild and
    strong AC electric current in terms of steady state creep rate under both compressive
    and tensile loading is demonstrated. A current density of 25 and 200mAmm 2isusedforthecreep
    deformation. The creep rate  increases by up to two orders of magnitude under
    electric current. The stress exponent remains unchanged for creep experiments
    at 1200 °C with and without electric current, suggesting a GBS mechanism of plastic
    deformation in both cases. The field-enhanced creep rate is attributed to the
    interaction of space charge layer and the electric field resulting in enhanced
    GBS. A higher current density results in enhanced ductility of GDC even when the
    Joule heating effect is compensated by reducing t"
