Abstract
A novel population balance model based on size interval-by-size interval ma rching algorithm has been developed for the transient grain growth kinetics during solid state sintering. This model incorporates the coupled phenomen a of densification and grain growth and exhibits reasonable capability of p redicting the temporal evolution of grain size distribution for a given ini tial grain size distribution and time-temperature sintering cycle. In this, part II of our work, we present the coupled governing equation for sinteri ng kinetics. We employ a size interval-by-size interval marching algorithm for the solution of the resulting population balance equation and validatio n of the model against experimental data for zirconia compacts sintered at 1400, 1500 and 1600 degreesC for different times. In addition, the model ha s been successfully tested against published experimental data on sintering of alumina compacts. (C) 2001 Elsevier Science Ltd and Techna S.r.l. All r ights reserved.
