Abstract

The effect of Zener drag on the grain growth process has been studied within the framework of the Wagner-Zlyosov-Hillert model. We find, as expected, that stagnation takes place, and we have studied how the limiting radius varies with Zener drag. We also demonstrate that previous models for the kinetics of the stagnation are unable to give a satisfactory description of the kinetics. We calculate the shape of the distribution function at stagnation and discuss how this is affected by the shape of the initial distribution function.
