It describes these mechanisms in qualitative terms, explaining how they are driven by thermal energy and how they can be analyzed using creep curves and deformation maps. In addition, it examines the types of damage associated with creep, presents a number...

.... If the temperature is below the creep range, damage components 2 and 3 will be absent and damage will occur under simple low-cycle fatigue (LCF). At higher temperatures, the fatigue curves have to be modified to take into account frequency and “hold time” effects. Typical LCF design curves for HP rotor steels...
