SPECIAL FRACTOGRAPHIC TECHNIQUES FOR FAILURE ANALYSIS

Abstract

Work was performed using electron fractographic methods to resolve problems that have not been solvable using the more conventional macro- or light microscope techniques. Three independant problems were examined, and solutions were achieved. These were: (1) Determination of fracture direction in thin sheet metal components. (2) Differentiating between hydrogen embrittlement and stress corrosion in high strength steels. (3) Determination of applied cyclic stress as a function of fatigue striation spacing.
