Abstract
A viscoelastic model that describes the shrinkage rate of large pores within a fine‐grained body has been developed. The concept is based on a shrinkage potential derived from the surface and grain‐boundary tensions and viscous response determined by the creep characteristics of the polycrystal. Pore removal rates are also derived and used to predict pore removal times during sintering and hot isostatic pressing.
