The report presents a summary of the following research efforts 1 a major effort was devoted to studying the synergetic effect of the gamma to alpha alumina phase transformation on pressure-sintering kinetics of high- density alumina ceramics. 2 An extensive program was also initiated with the purpose of relating diffusion coefficients observed for ceramics subjected to pressure-sintering or press-forging operations with interdiffusion coefficients observed in diffusion experiments. 3 In addition to the studies on basic mechanisms in the densification kinetics of ceramics, considerable attention was also devoted to studies of the mechanical behavior of ceramic materials. 4 Additional studies of the mechanical behavior of ceramic materials involved an analysis of fracture energies.
