ON THE FATIGUE LIMIT BEHAVIOR OF IRON AND MILD STEEL.

Abstract

A critical review of research in recent years on the fatigue limit behavior of iron and mild steel is combined with experiments on zone-refined iron to demonstrate the importance of interstitial-dislocation reactions to the nature of the fatigue limit. The controversy over whether the fatigue limit in ferritic materials results from a characteristic peculiar to the iron (bcc) lattice or results from strong initial dislocation locking and dynamic strain aging is somewhat clarified. It is shown that each of the extant ideas have some merit, and that each of the mechanisms thus far proposed are necessary, but individually insufficient, to provide the desired level of understanding of the fatigue limit behavior of metals.
