Abstract
In this review, the fatigue failure process will be treated in two basic stages, namely crack initiation and crack propagation. Depending upon how crack detection is made - by the naked eye, an eddy current device, a metallographic microscope or an electron microscope crack initiation may be defined as a crack length anywhere between 1/8" and 1000 Angstrom. In this review, it will not be attempted to define a fixed crack size as the criterion of initiation, but the scale on which the various mechanisms of microcrack initiation operate will be discussed.
