The Quantitative Evaluation of Grain Boundary Phases by Cryogenic Specific Heat Measurementss. The specific heat of three types of Si.N. ceramics treated by different processes from the same raw powder and with the same amount of Y.O. and AI.O. additives was measured at different temperatures between 10 and 50 K. The difference between the measured specific heat and the calculated specific

The Dependence of the Internal Friction and the Mechanical Properties of Ceramics on their Grain Bounternal friction at high temperatures was strongly dependent on the grain boundary characteristics, such as grain boundary softening, sliding, and the diffusion of ions in the constituents of the grain boundaries. Creep rate and strength at elevated temperatures were also dependent on grain boundary

α‘ /β’ Sialon Composites MPa for 1 to 10 hours. X-ray diffraction analysis indicated that the hot-pressed bodies were composed of Y–α’-sialon and β’ -sialon. The amount α’ -sialon increased as the amount of Y.O. and AlN were increased. The lattice constant (solubility) of α’-sialon depended on the amount of Y.O. and AIN, w

The Effects of Grain Size on Strength, Fracture Toughness, and Static Fatigue Crack Growth in Aluminigate the effects of grain size on bending strength, fracture toughness, and static fatigue crack growth rate. The bending strength increased with decreasing grain size. The validated fracture toughness is independent of grain size. On the other hand, the apparent fracture toughness with slow crack

Influence of Environment on Strength of Ceramics time has led to the development and use of novel ceramic materials both in the monolithic form and as composite constituents. Many of these applications involve exposure to environments containing hydrogen, water vapor and other aggressive species. In this paper, the effects of hydrogen-containing
