Abstract : This is the final report arising from our research program involving the investigation of processing/microstructure relationships in selected ceramic systems. The first year of this program was dedicated to the development and detailed assessment of the novel neutron scattering and x-ray diffraction techniques required for the measurement of ceramic microstructure evolution as a function of sintering and chemistry. The next two years of the program were used to study several systems in detail, and has led to some remarkable conclusions which have changed the way in which the sintering stages in different systems are understood. The sintering behavior of a ceramic body and the properties of the ceramic product depend directly on the internal microstructure. The goal of our research program with the ARO has been to investigate well-characterized systems and to measure microstructure evolution during ceramic processing in order to obtain an improved understanding of the relationships between processing and microstructure. This approach has led to progress in improving process models and to improved predictability of product microstructure.
