Fig. 1. Evolution with cold drawing of macro-crack path profiles in progressively cold drawn pearlitic steel wires (HAC environmental conditions): (a) general appearance of the fracture surfaces; (b) geometric parameters describing the crack path; (c) evolution of fracture profiles; f: fatigue crack growth; I: mode I cracking; II: mixed mode cracking; F: final fracture by cleavage at the critical situation (Toribio, 2017).
