Abstract
The Lifshitz-Slyozov-Wagner (LSW) theory was developed to model kinetics of precipitate growth from supersaturated solid solutions. The theory corresponds to a zero volume fraction approximation but has been modified for finite volume fractions in order to correspond to real situations. The LSW theory has been applied to study coarsening of grains in liquid-phase sintering and to the coarsening of pores in solid-state sintering systems. There are some additional factors not considered in the LSW theory which can influence the coarsening kinetics depending on the system. It is important, therefore, to incorporate these factors into a coarsening model for better analysis of experimental data. The experimental evidence for the effects of these additional factors is reviewed together with the theoretical modifications made to the basic LSW theory in order to incorporate these factors.
