Summary
A technique is described for establishing the microstructural features associated with the initiation of brittle fracture in weld metal and heat-affected zone (HAZ) crack-tip opening displacement (CTOD) test specimens. The technique involves detailed optical and scanning electron microscope examination of fractographic features to establish the local directions of fracture propagation at various locations on the fracture surface. This information is used to trace fracture propagation back to the region of initiation. In many instances, the precise initiating feature can be located and identified. Once identified, the fracture initiation position is marked and the specimen sectioned through this point to allow the region in which fracture initiated to be examined metallographically and related to the surrounding microstructure. Details of the technique are discussed.
