| Abstract Scope |
The electric field assisted sintering (EFAS) process involves tightly coupled physics that influence microstructural evolution in the particles being compacted. The simultaneous application of heat, electric field, and external pressure dramatically accelerates densification while achieving significantly reduced energy input required to achieve it. It is also an inherently multi-scale phenomenon, with the microstructure of the compact influencing the subsequent engineering-scale response of the sintering system. To improve understanding of how processing parameters influence microstructural evolution, we have developed phase-field modeling approaches to capture the impact of these driving forces on microstructural evolution. The modeling approaches have been applied to ceramics, where ionic conductivity of charged defects dominates the electric response, as well as metal-ceramic granular mixtures, where electrical conductivity dominates. Strategies for up-scaling the phase-field simulations to engineering-scale modeling of response will also be presented. |
