Abstract
The method is based on transcapillary penetration of fluorescent fluid (EpoDye colorant) in the finest cavities and flaws on the surface of polished sections. Luminophor-filed voids become visible under UV light and optical microscope. The voids are estimated with respect to their kinds, sizes and area. The estimates and the statistical property of void distribution are described.
