| Abstract: | With a new Monte Carlo algorithm, the three-dimensional normal grain growth pro cess including the steady-state stage is appropriately simulated. The topological dependence equation for the growth rate of three-dimensional individual grains, which was first derived theoretically by the presents authors and can be considered as a three-dimension equivalent to Von Neumann's equation in twos-dimensions, is confirmed by means of the simulation. Such verification with experimental measurement in real microstructures is not available yet. |
