Before revision: Conrad and Li found that the activation energy for grain boundary sliding increased by nearly 20%DIF < under the application of a 2 kV cm^{-1 Electroplasticity in Ceramics The application of electric fields to ceramics can give rise to plasticity in materials that traditionally exhibit no plastic deformation.
