Fig.16. Fatigue crack initiation from different configurations of the MnS particles^[74](a) cracks are along single ellipsoidal MnS inclusion when the load axis is perpendicular to the sulphide(b) cracks emanates from the chain-like type MnS inclusions when the load axis is perpendicular to the sulphides(c, d) no crack emanates from the sulphide when the load axis is parallel to the particles
