摘要
A model has been developed to describe the effect of the matrix pore distribution on microstructure development in the final stages of sintering. A model of simultaneous densitification and grain growth was used to predict the effect of the number of pores per grain and the pore size distribution on microstructure evolution. Increasing the number of pores per grain was predicted to increase the densification rate, the grain growth rate, and the relative densification rate/grain growth ratio.
