Sintering and deformation properties of forsterite + diopside aggregates in an electrical field

Promoting effects of alternating current and input power on grain growth behavior of cubic ZrO2 polycrystals

“…In contrast, athermal effects that cannot be explained by temperature increments due to the Joule heating have also been suggested to promote atomic diffusivity in materials. 6 For example, high-temperature processes, such as enhanced plastic deformation, [7][8][9][10][11][12][13][14] diffusion joining, [15][16][17] and crack healing [18][19][20][21] of fully densified yttria-stabilized zirconia (YSZ) materials, have already been achieved at lower temperatures and in shorter times. Therefore, during the flash event, cation diffusion, which is regarded as the rate-controlling process in high-temperature processes, is expected to be promoted athermally by applying an electric field and current.…”
