This comprehensive and in-depth work details state-of-the-art intermetallic compounds, from mechanical properties and alloy development to processing and structural applications. Emphasizing the role of processing in developing microstructures and optimizing mechanical behavior, experts from a variety of disciplines: * detail environmental effects on mechanical properties, especially those caused by hydrogen and moisture * enable appropriate selection of materials for specific applications by comparing intermetallic behavior with that of other high-temperature materials such as superalloys and composite ceramics * describe powder and melt processing, as well as the mechanical working of intermetallics * offer insights into major developing intermetallic alloy systems, with particular focus on aluminides and silicides * examine creep, fatigue and fracture of intermetallic materials.
