This paper reviews the current state of the art of high temperature fatigue. Attention is given to the relative rotes of crack initiation and crack propagation, to damage processes resulting from cyclic strain including that of the substructure, of cyclic strain aging, at grain boundaries, by the environment, from wave shape effects and from plastic instabilities. The phenomenology of high temperature fatigue discussed includes formulation of fatigue equations and material representation, effects of environment, role of frequency, and of wave shape. The state of fatigue life prediction methods is considered with attention given to the most recent approaches to the problem.
