A Topological Study of Grain Growth.
Abstract
The characterization of the topological properties during isothermal grain growth has made it possible, for the first time, to describe grain growth as a topological process and to define its kinetics. Grain growth has been associated with a topological change in which the average topological values per grain in the system approaching limiting values equivalent to those of a tetrakaidecahedron. Experimentally it is found that the product of the total curvature per unit volume and the surface area per unit volume maintains a constant ratio to the grain size constant. Grain growth has been described in this study as taking place in two modes: steady and non-steady state. These relationships have led to the development of a new kinetic equation for grain growth.
