Syllabus
Introduction to Structural Ceramics, Important structural ceramics in oxide and non –oxide ceramics. Alumina ceramics effect of microstructure and strengthening and toughening – thermal expansion anisotropy and micro-crack toughening. Zirconia Ceramics- polymorphic modifications, stabilization and toughened zirconia. Composites: strengthening and toughening mechanisms, composite fabrication. Composites of some oxides and non-oxides. Non-oxide ceramics- classification, issues of densification. Reaction bonding and non-oxide ceramics fabrication. Discussion of important non-oxide ceramics- silicon carbide, silicon nitride Sialon, Boron Carbide, Boron Nitride, phase diagrams, processing, sintering and properties. Failure analysis, fractography, Friction and Wear. Importance of design consideration, material selection and failure analysis for application and reliability of structural ceramics. Weakest link theory, probabilistic design, and Weibull modulus. Strength and toughness –different methods, limitations, and effect of test protocol and sample specification of strength and toughness. Thermal shock resistance – the effect of material parameter and microstructure. The standard protocol of thermal shock measurement tests.
