Estimation of volumetric content of phases from random cross sections

In this paper we present an experimental evaluation of the applicability of the stereological principle (equality of area and volume ratios) for low contents of the studied phase and various textural and structural parameters. This principle works well for uniformly distributed ellipsoidal particles. In other cases, it is necessary to apply a correction factor to the average values of the phase ratios determined from sections. This factor depends on textural and structural characteristics.
