Fatigue and Durability of Metals at High Temperatures

Fatigue and Durability of Metals at High Temperatures is a repository of knowledge, experience, and insights on high-temperature fatigue and its effect on component lifetime and failure. The first few chapters provide readers with an intuitive understanding of creep and creep-fatigue and how they progress based on time, temperature, and stress. In subsequent chapters, the authors present several fatigue life prediction techniques, comparing them to each other and to experimental test results. The authors focus on a method called strain-range partitioning that breaks stress-strain hysteresis loops into simpler components, the effects of which can be analyzed more easily. Through detailed examples, they show how strain-range partitioning can account for creep-fatigue interactions, multiaxial stresses and strains, temperature gradients, metallurgical and microstructural changes, thermal fatigue, and damage mitigation or “healing” due to sequential loading. The method is also used to examine the cyclic deformation characteristics of various steels and alloys and the obstacles to achieving high-temperature structural durability with fiber-reinforced metal-matrix composites.
