Book excerpt: Emphasis is on the discussion and analysis of the processing and properties of multiphase structural ceramic materials and metal matrix composites reinforced with ceramic particulates or fibers. This volume represents the state-of-the-art in our understanding of the processing-structure-property interrelationships for these materials which possess unique and useful mechanical and thermal properties as a result of their multiphase nature. Additionally, the reader will find useful information on many new materials and processes currently under investigation.
