Role of Non-Metallic Inclusions in the Fracture Behavior of Cold Drawn Pearlitic Steel

In this paper an exhaustive scientific work is performed, by means of metallographic and scanning electron microscope (SEM) techniques, the microstructural defects exhibited pearlitic steels their evolution with manufacturing process cold drawing, analyzing consequences such on isotropic/anisotropic fracture behavior different steels. Thus, objective establishment a relation between damage To end, samples were taken from all intermediate stages real drawing process, initial hot rolled bar (not drawn at all) to heavily final commercial product (prestressing steel wire). Results show very relevant role non-metallic inclusions in
