## Description

- description: The effect of the flash event on grain growth behavior was examined
    in 8 mol% yttria-stabilized cubic zirconia (8Y-CSZ) polycrystals under direct
    and alternating electric fields/currents. Even at the same specimen temperature,
    the rate of the grain growth is accelerated in the flash event than in the heat
    treatment without electric field/current (0 V), suggesting that the non-thermal
    effect caused additionally under the flash event contributes to the acceleration
    of the grain growth. Although the grain growth behavior can be characterized by
    the empirical equation (d_t^n –d_0^n = kt) with the same grain growth exponent
    of n = 3 irrespective of the electric field/current, the activation energy for
    the grain growth is lowered under the flash event. This suggests that the non-thermal
    effect caused by the flash event does not affect the mechanism of the grain growth,
    but would accelerate the rate-controlling process of the grain growth. The non-thermal
    effects can be further accelerated in fine-grained specimens under the alternating
    current flash and/or by increasing the input power density. Since the grain growth
    is rate-controlled by the grain boundary cation diffusivity, the non-thermal effect
    under the flash event would accelerate the grain boundary cation diffusivities
    through the formation of excess oxygen vacancies depending on the polarity and
    the power density.
