Microstructural dynamic study of grain growth

PDF Version Also Available for Download.

Description

A simulation procedure for grain growth has been developed which accounts for local structure and topology. The simulated microstructures show excellent agreement with those found in isotropic polycrystalline metals and ceramics. The grain size distribution, topological distribution, and the topology-grain relations are all in excellent agreement with experiment. Similarly, the kinetics found also reproduce the experimental results. It is suggested that the growth exponent, n < 1/2, is inherent to the grain growth process and is not due to impurities, preferred orientation, etc. as had been previously thought.
