Description
Summary:Three levels of description of the geometric state are considered in discussing the “three-dimensional topography” of a microstructure. The first level is simply a list of the features that exist in the structure; the second associates with each member of this list, numbers that describe its extent or configuration; the third is a complete description in terms of the distribution of features in space. Experimentally, most of the metric properties may be estimated from counting measurements made upon a representative microsection; whereas the topological properties require a serial sectioning analysis. The counting measurements are then combined with some elementary statistical analysis in order to describe anisotropies, gradients, and spatial relationships between microstructural features.
