The specimens were prepared of a kindof triangular shape in which the surface tensile stress is a constant. The resultsshow that the short fatigue cracks originate from the slip bands and initiate insidethe ferrite grains. The development of short fatigue cracks is marked by the grad-ual increase in crack density with fatigue cycles. The coalescence between shortcracks leads to crack propagation and the crack path is predominantly transgranular.
