Self-Similarity as a Feature of Nanocrystalline Grain Growth

Abstract:

In the present work it is revealed by modified Potts model simulations and theoretical considerations that self-similarity is a feature of junction controlled grain growth as it can be found in nanocrystalline materials. To this aim the influence of the grain junctions – boundary faces, triple lines and quadruple points – on grain growth is analyzed by attributing each type of junction an own specific energy and mobility yielding nine types of growth kinetics, each characterized by a self-similar scaling form of the growth law and a corresponding self-similar grain size distribution.
