Abstract

Three-dimensional grain growth was analysed using the Surface Evolver program that simulates grain-boundary motion by curvature. When the grain-boundary network reached a statistically self-similar steady state structure in the normal grain growth period, the mean life span until the disappearance of grains could be predicted from the distribution function of the normalized grain size and the distribution function of the number of faces in normal grain growth period.
