摘要：
A model of sintering by volume diffusion has been developed in which finite element analysis is used to evaluate the chemical potential distribution throughout crystalline sinter body, subject to boundary conditions specified by surface curvature. Although the analysis leads to a dynamic simulation of sintering, it may also be used to study sintering processes in static (fixed geometry) systems. The dynamic sintering model was applied to the intermediate to late stages of sintering of lines of spheres and cylinders. The static mode of the model was used to display the chemical potential distribution and flux paths during various stages of neck growth.
