Resumen: Recent availability of automatic or semi-automatic image analyzers has brought to attention the possibility of developing methods for the quan tification of geometrical characteristics not only of plane sections - quan titative metallography has be en long known and used - but also of non-pla-nar surfaces as those which are obtained as a result of fracture. There are two main approaches to this problem, one is based on the evaluation of unidimensional parameters of profiles which are obtained as a result of vertical sectioning of fracture surfaces and leads to the measu rement of roughness parameters or fractal dimensions, and the other one isbased on direct determination of parameters of the fracture surface with the help of stereo pairs or 3-D reconstruction techniques. The interest of our group is directed more towrdsthe latter approach, taking into account the facilities now available which include the possibility of directly feeding electron images from the SEM into the image analysisunit. No results have been produced so far, but projects which will include this possibility of a direct geometrical analysis of fracture surfaces to relate them to the microstructure and to mechanical properties will be considered in the near future.
