Microstructure development during final/intermediate stage sintering. II. Grain and pore coarsening
Journal Article
·
· Acta Metall.; (United States)
The rates of grain and pore coarsening and of pore shrinkage that occur during sintering have been analyzed in the presence of porosity at three-grain junctions. Optimum sintering conditions that exclude pore coarsening have been identified. The pore coarsening that occurs under sub-optimal sintering conditions depends on the dominant diffusivities, the grain boundary mobility and the dihedral angle. The pore sizes that develop during sintering have been compared with the critical pore size for pore-grain boundary breakaway, and conditions for averting breakaway discussed.
