“…Among the methods developed for assessment, the time-temperature-parameter (TTP) method is most commonly used. As 9-12 %Cr heat-resistant steels Vaillant et al 2008) have been quickly developed to manufacture the components that can withstand severe service conditions, Yagi (2008) has found that the TTP method shows a risk of overestimating the allowable creep strength of the materials in service at high temperature. This causes the so-called 'premature failure' .…”

This chapter introduces the various topics included in the book, in subsequent chapters. As the research book assumes that the reader has graduatelevel materials science knowledge, this is not discussed in the introduction chapter here. Instead, the introduction focuses on different types of steels, including conventional heat-resistant steels, silicon-bearing high chromium heat-resistant steels and nitride-strengthened reduced activation heat-resistant steels. Topics relevant to service conditions and behaviour of steels follow, in thermal ageing, microstructural stability and creep. Finally, the hot deformation processing of steels is discussed. The chapter can be read independently of the rest of the book, but, with its wide referencing, it is also useful in assisting in reading the in-depth chapters that follow and being referred back to. Directly referring to later chapters and sections helps with the latter.

“…The change in slope of the curve of time to rupture vs log(stress) with changing failure mode has been widely documented for many years [9], and continues to attract interest [10][11][12][13]. An ideal representation of the creep process throughout the full tested stress range might therefore be by a series of continuous functions that coincide at the changeover stress/ temperature boundaries for different failure modes.…”
