COMPUTER SIMULATION OF TOPOLOGICAL EVOLUTION IN 2-D GRAIN GROWTH USING A CONTINUUM DIFFUSE-INTERFACE FIELD MODEL

摘要

The local kinetics and topological phenomena during normal grain growth were studied in two dimensions by computer simulations employing a continuum diffuse-interface field model. The reationships between topological class and individual grain growth kinetics were exsamined, and compared with results obtained previously from analytical theories, experimental results and Monte Carlo simulations. It was shown that both the grain-size and grain-shape (side) distributions and time-invariant and the linear relationship between the mean radii of individual grains and topological class n was reproduced.
