Abstract:

This report summarizes the results of a two-year research program devoted to an investigation of the effect of compositional and microstructural variables on the thermal conductivitydiffusivity and its temperature dependence of structural ceramics. A total of twelve completed studies have resulted from this program, as follows 1 Effect of Temperature Dependence of Thermal Conductivity on Thermal Stress Resistance of Brittle Materials, In Particular Aluminum Oxide 2 Effect of Matrix Conductivity on Radiation Heat Transfer Across Pores 3 The Thermal Diffusivity of Al2O3-Cr2O3 Solid Solutions 4 Effect of Micro-cracking on the Thermal Diffusivity of Fe2TiO5 5 Role of Thermal Diffusivity in the Performance of Ceramic Oxide Cutting-Tool Materials 6 Thermal Diffusivity of Non-Stoichiometric Titanium-Dioxide 7 Thermal Diffusivity of Si-Al-O-N Compositions 8 Thermal Diffusivity of Glassy Carbons 9 Effect of Micro-cracking on the Thermal Diffusivity of Polycrystalline Aluminum-Niobate 10 Effect of Micro-cracking on the Thermal Diffusivity of MgTi2O5 11 Micro-cracking as a Mechanism for Improving Thermal Shock Resistance and Thermal Insulation Properties of Ceramic Materials 12 The Effect of Microstructure and Composition on the Thermal Diffusivity of Structural Ceramics.
