Fatigue behavior of metals is reviewed with particular emphasis on those properties and parameters which relate to cyclic deformation resistance at high temperature. The strainrange partitioning method, a tool for characterizing high- temperature, low cycle fatigue, is employed to propose a design critérium to be used in structural applications when high fatigue stress or strain rate and relevant temperature occour. The advantage of this method is that it allows an approach to problems involving arbitrary variations of strain and temperature as a function of time.
