| Abstract: | The modifying effect of dihedral angle on the morphological stability of continuous pore channels along three-grain junctions was evaluated and quantified. Breakdown of a continuous pore channel is possible when perturbation wavelengths exceed a critical wavelength, λmin, which is found to depend on dihedral angle. The implications of the analysis to microstructure development during sintering are briefly discussed. |
