Abstract
The topological transformation of grains in three-dimensional normal grain growth was analyzed by Brakke's Surface Evolver method that simulated the b oundary motion by curvature. The statistics on elemental processes, which c hange the number of faces f of a grain, were determined from the simulation . The distribution function of the number of faces P(f) in a steady structu re could be predicted from the difference in the current of grains arriving at and leaving from state f: For the disappearance of one grain, face-crea tion switching occurred 3.7 times and face-elimination switching occurred 1 3.2 times on the average.
