| description | The brittle failure of a crankshaft was investigated. The chemical
composition and material properties of the crankshaft were analyzed.
The hardness profile indicated that the manufacturer used the
crankshaft as cast without heat treatment. The chemical composition
and material parameters were compared with those found in the
literature for similar applications. The yield strength, tensile strength,
and hardness values observed for the crankshaft were lower than
those observed in other crankshafts in the literature. The chemical
analysis revealed that the Si composition deviated from the
composition in the literature for a typical crankshaft material.
Furthermore, low modularity and irregular nodule distribution were
observed. The main reason for this failure was the poor mechanical
properties arising from the chemical composition, processing, and
inoculation characteristics.
