In order to clarify the effect of small prestrain on the fatigue strength of carbon steel, fatigue behavior of plain specimens of eutectoid steel subjected to tensile prestrains is investigated, and compared with that of annealed or strain-aged specimens. It is found that small prestrain of a few percent does not decrease either the fatigue limit or the crack initiation and propagation lives. Fatigue slip initiation, however, is accelerated by the small prestrain. It is also found that no cyclic strain aging occurs. From these results, it is concluded that dislocations are unpinned by the small prestrain and this causes fatigue slip to occur easily, but the fatigue behavior after the slip initiation is not affected because spheroidal cementite acts as obstacles to further slip deformation and the stage I crack propagation.
