Interface Morphology in Ceramics
Modern ceramics find more and more technological applications as substitutes for metals. Normally these ceramics belong to the group of non-equilibrium multicomponent multiphase systems. Due to this state of non-equilibrium,chemical transport processes like diffusion within the phases and across the interface can occur during manufacturing or during use at high temperatures. Since in multicomponent systems interfaces may be morphologically unstable, quite irregular interface structures can evolve from regular, planar interfaces. This microstructural evolution may affect the mechanical stability or the electrical properties of the material, for example, and will have to be taken into account when designing engineering parts.
