Abstract

Fatigue properties of compacted graphite cast irons are related to the free graphite configuration. Compacted graphite irons, owing to their intermediary structure, exhibit mechanical properties that lie between those of gray and nodular irons. Two different CG irons were fatigue tested and the resulting variance in their response related to dissimilarities in their graphite morphology.
