Electric current dependence of plastic flow behavior with large tensile elongation in tetragonal zirconia polycrystal under a DC field

This study systematically investigated the electric direct current (DC) dependence of plastic flow behavior in a densified tetragonal ZrO2 polycrystal (TZP). Consequently, we observed an optimal density for tensile ductility. The maximum elongation 135% was achieved under 250 mA?mm?2 at furnace temperature 1000°C and initial strain rate 1 × 10?3 s?1. diffusional mass transport TZP accelerated by combination Joule heating applied effect, resulting reduced stress improved
