Abstract: This paper analyzes how the cold drawing process influences the fatigue behaviour of eutectoid steel, with special emphasis on the role of microstructural changes induced during such a manufacturing process. Fatigue cracks are transcollonial and exhibit a preference for fracturing pearlitic lamellae, with non-uniform crack opening displacement values, micro-discontinuities, branchings, bifurcations and frequent local deflections that create microstructural roughness. The net fatigue surface increases with cold drawing due to the higher angle of crack deflections.
