Abstract : Methods and capabilities of electron microscope fractography were investigated so that the potential use of fractography could be determined. Work of other investigators was studied, equipment was set up, and the application of two- and three-stage replication techniques was evaluated. Electron microscope fractographs made by the first method are shown. Modes of fracture are discussed and diagnostic features of each mode, visible with the electron microscope, are described with references to pertinent literature. Characteristic features of fracture surfaces are illustrated by electron microscope fractographs. (Author)
