| Abstract Scope |
This study investigates the effects of heating rate and electric fields on the flash sintering of zirconia and 8% yttria-stabilized zirconia (YSZ) nanoparticles through both molecular dynamics modeling and experimental analysis. Molecular dynamics simulations explored the influence of varying temperature ramp rates on activation energy and sintering rate. Experimental investigations, including flash sintering conducted in a custom-designed tube furnace capable of heating up to 1300°C at rates up to 40°C/min, provided insights into the electric field’s impact on grain size and orientation. Additionally, in-situ SEM observations of flash sintering mechanisms were conducted to further understand the microstructural changes. The findings highlight the combined influence of thermal and electric field effects on the sintering behavior of both zirconia and 8% YSZ, providing a comprehensive understanding of the process. |
