Abstract
The sweep constant in grain growth, theta, is defined as the number o f grains that disappear when the grain boundaries sweep through a tota l volume equal to that of the average grain. An analytical derivation is presented that expresses theta for self-similar grain growth solel y in terms of the self-similar size distribution. Specific application s of this analysis are presented, and the implications of these result s with respect to grain growth kinetics are discussed. (C) 1997 Acta M etallurgica Inc.
