Abstract
A model is proposed to describe the time dependence of the average interface migration rate observed during recrystallization. The main assumption is that the growth rate of the extended grains can be written as a function of the recrystallized fraction. From this assumption, it could be demonstrated that the average interface migration rate can be written as a product of two factors. One is a time-independent but temperature-dependent interface migration rate. The other factor can be made a function of normalized time only and therefore is independent of temperature. The model shows good agreement with the results of Speich and Fisher and Vandermeer and Rath. It is concluded that the present model offers a plausible description for the time dependence of the average interface migration rate in recrystallization.
