Abstract

A variable model for random two-phase structures with arbitrary volume fraction is presented. The model is capable of creating both fractal and non-fractal polydisperse arrangements. It is used to analyze experimental data on the microstructure of dense silicon nitride ceramics investigated by means of scanning electron microscopy and small-angle neutron scattering.

Keywords : ceramics, fractals, image analysis, small-angle scattering
