Local Chemical Bonding at Grain Boundary of Si3N4 Ceramicsomputational result is twofold: 1) On the basis of our calculations using model clusters, the Si-L. edge ELNES of the intergranular glassy film reported in literature is interpreted; The N/(O+N) ratio of the intergranular glassy film is found to be in the range of 30 to 40%. A model of atomic arrang

Design and Life Prediction Issues for High-Temperature Engineering Ceramics and Their Compositeson requirements and their role in directing research. Important themes include the relative roles of fracture toughness and inelastic strain (ductility), as well as scaling and stochastic effects caused by manufacturing defects. Ceramics with high toughness have been developed. But, because they are

Anion Segregation at Si3N4 Interfaces Studied By High-Resolution Transmission Electron Microscopy anThe materials required hot-isostatic pressing (HIPing) for complete densification since they contained no external sintering aids except a small fraction of anions, ., fluorine or chlorine. These materials are considered a model system, because the non-crystalline secondary phase between Si.N. grain

Grain-Boundary Films in A Silicon Nitride Ceramic at High Temperatures50°C for various times and then quenched to “freeze-in” the high-temperature microstructure. The grain-boundary film thickness was found to depend on temperature and residence time prior to quenching. Rapid heating to temperatures just above the eutectic temperature, followed shortly by quenching, r

Microstructure and Intergranular Phase Distribution in Bi2O3-Doped ZnOl tools. In solid-liquid equilibrium, the capillary (sphering) pressure is systematically varied by controlling grain size and liquid fraction. Intergranular phase thicknesses and dihedral angles are found to vary with capillary pressure, a phenomenon which can be understood from the effect of appli
