Nano-polycrystals constitute a promising group of engineering
materials. The basis for definition of these materials is their grain
size. This calls for analysis of grain size measurements of fine
grained structures. The paper addresses the following aspects of the
grain size measurements:
* parameters used for definition of grain size (volume, surface,
surface to volume),
* grain size distributions, the mean grain size and grain size
* imaging of grain boundaries on sections and thin slices,
* parameters measured on images (grain section area, grain section
parameter, intersections with test lines),
* stereological methods (SALTYKOV, BUCKI, vertical sections,
* weighted estimates (point sampled intercepts, triangles)
* modeling processes and properties (migration of grain boundaries,
grain growth, abnormal grain growth)
Examples are included which are based on studies of metals, ceramics
and composites.
