Kinetics and Mechanisms of Synergetic Pressure-Sintering and Mechanical Behavior of High-Strength Ceramics

Abstract

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.
