    Uses of the electron microscope for the study of fracture surfaces and the subsequent formulation of models of fine-scale fracture mechanisms are demonstrated. Electron fractography is shown to be a valuable tool in obtaining a better understanding of fracture and in the analysis of service failures.

    Various types of fracture surfaces produced by single-cycle overload and by fatigue in various materials are discussed in order to indicate the usefulness of this relatively new tool.

    The scope of application in the general field of fracture research is indicated.
