SUMMARY The methods of quantitative metallography and stereology have been used to determine the distribution of the diameter of equivalent spheres and hence study the change in particle size of titanium carbide undergoing growth/coarsening in a nickel matrix. The distribution obtained, using the Saltykov method, is in agreement with that proposed theoretically by Hanitzsch for the kinetics of growth controlled by an interface reaction. The change in the Smith shape factor shows that growth of titanium carbide is isotropic. This is thus an example of the possibilities offered by stereology. The crystal size distribution in three dimensions is closest to the theoretical models.
