Case History—Peer-Reviewed


A fractured extruded brass (CuZn39Pb3 alloy) hexagonal rod of 6 mm across flats (AF) was received with the request to perform a failure investigation. Visual inspection, and optical and scanning electron microscopy/local elemental x-ray analysis (SEM/EDS) were used as the principal tools for the investigation. Metallographic and fractographic observations indicated the occurrence of brittle intergranular fracture. The collected evidence suggests that hot shortness is the failure mechanism.
