Abstract

The stochastic field approach describes grain growth in polycrystalline materials as a stochastic process in volume time space. A stochastic process represented by a Fokker-Planck equation in volume time space automatically conserves the volume of the specimen. The stochastic component of grain growth becomes proportional to the variance of the volume growth rate and to unit time. The present paper examines various stochastic models of grain growth in the light of the stochastic field approach.
