This article deals with the analysis of the evolution of intracolonial micro-defects produced in pearlitic steel wires as a direct result of the cold drawing process. The study was carried out from the observation of the microstructure of wires belonging to the different steps of a real cold drawing chain, formed by seven stages of cold drawing. The evolution of intracolonial micro-defects can be key in the subsequent fracture process of the cold drawn pearlitic steel. The analysis of these micro-defects has been carried out after the observation and study of micrographs belonging to these wires. Scanning electron microscopy (SEM) techniques have been used to obtain micrographs.
