This book brings together the theoretical aspects of high-temperature damage phenomena and the practical aspects of assessing the actual damage on a component-specific basis. The first four chapters lay the theoretical foundation with respect to toughness, embrittlement phenomena, creep, fatigue, and creep-fatigue interaction.
