    Phase mixture models and unit-cell calculations for the effective elastic and thermal properties of nanocrystalline ceramics

  • Original language description

    The properties of nanocrystalline ceramics are in many respects unique because the grain boundaries, which are in reality discontinuities of small but finite thickness, attain significant volume fractions when the average grain size is below approx. 100nm. The simplest way to model the grain size dependence of properties consists in considering the nanocrystalline material as a two-phase composite, i.e. as a binary mixture of two separate phases, a crystalline core phase (with properties correspondingto the bulk solid) and a disordered, glass-like grain boundary phase. When this viewpoint is adopted, the laws of composite theory (micromechanics) can be applied to estimate the effective properties. In this chapter this is done for single-phase ceramicsystems with monodisperse grain size by invoking a unit-cell approach using cubic, tetrakaidecahedral and anisometric grain shapes (trigonal, tetragonal and hexagonal prisms, oblate and prolate). In particular, the effective Young?s modu
