In this paper a failure analysis investigation is presented regarding the intergranular cracking of three different diameter (Ř26.6, Ř10.8, Ř8.5mm) extruded brass rods which failed after extrusion. Optical, electron microscopy and Electron Backscatter Diffraction are employed in order to reveal the mechanisms and the root cause of the failures. The microstructural characteristics exhibited by the brass rods (phase and grain structure and distribution of intermetallic particles) are considered to exert a detrimental effect, contributing to the degradation of mechanical properties assisting the occurrence of brittle fractures. Revision of preheating and extrusion conditions could be further implemented in order to minimize the risk of future failures.
