Case History---Peer-Reviewed


A permanent mold cast Al 356-T6 aluminum clutch pedal lever is investigated to determine the mode of failure. The part is investigated using visual inspection, metallography, scanning electron microscopy, energy dispersive spectroscopy, and hardness (HRB) testing. The part is found to have casting defects ranging from extreme porosity to intergranular fusion voids causing brittle fracture of clutch lever.
