Book Description
Two low alloy steels, heat treated to yield strengths approximating 175,000 and 150,000 psi, were fatigue tested under rotating beam conditions at temperatures of 70, 400, 600, 800 and 1000 F. The fatigue data is related to the tensile properties at various test temperatures. Temper embrittlement, occurring during the course of fatigue testing and its effect on the fatigue properties, is also demonstrated. For the steels investigated, the elevated temperature tensile properties appear to be good predictors of elevated temperature fatigue behavior. However, the occurrence of a subcritical temperature phenomenon to which the specific steel is susceptible (such as temper embrittlement) will affect the fatigue behavior and destroy its fatigue-tensile relationship.

Book Description
About 35 years ago, thermal fatigue was identified as an important phenomenon which limited the lifetime of high temperature plant. In the intervening years many investigations have been carried out, primarily to give guidance on likely endurance (especially in the presence of time dependent deformation) but latterly, with the introduction of sophisticated testing machines, to provide knowledge of the underlying mechanisms of failure. A previous edited book (Fatigue at High Temperature, Elsevier Applied Science Publishers, 1983) summarised the state-of-the-art of high temperature fatigue testing and examined the factors influencing life, such as stress state, environment and microstructural effects. It also considered, in some detail, cyclic crack growth as a more rigorous approach to life limitation. The aim of the present volume (which in style and format follows exactly the same lines as its predecessor) is once again to pursue the desire to translate detailed laboratory knowledge into engineering design and assessment. There is, for example, a need to consider the limitations of the laboratory specimen and its relationship with engineering features. Many design procedures still rely on a simple endurance approach based on failure of a smooth specimen, and this is taken to indicate crack initiation in the component. In this volume, therefore, crack propagation is covered only incidentally, emphasis being placed instead on basic cyclic stress strain properties, non-isothermal behaviour, metallography, failure criteria and the need for agreed testing procedures.
