title = "Fatigue behavior of carburized steel at long lives",
abstract = "The fatigue behavior of two carburized steels is investigated with rotating bending tests for lives between approximately 105 and 108 cycles. Cracks are observed to start at sub-surface inclusions within carburized cases and form “fish eyes” often seen in high cycle fatigue of hardened steels. Optically dark areas (ODAs) are found surrounding the inclusions that acted as crack origins. Fatigue strengths are evaluated by Murakami{\textquoteright}s √area model, but accounting for the influence of residual stress and hardness at the different depths at which cracks started. Values of stress intensity factor range at the periphery of inclusions and the outer border of ODAs are computed accounting for the influence of residual stress. Possible factors that may influence crack growth within ODAs are discussed.",
