To this end, wires belonging to different stages of the manufacture chain were studied, starting from an initial hot rolled bar (not cold drawn at all). In addition to the information obtained through visual inspection, a quantitative analysis of the micro-defects generated by these inclusions has been carried out. The analysis has been performed using materialographic techniques, scanning electron microscopy (SEM) and the image analysis program (AnaliSYS 3.1 ® )..

1. Introduction 1. Introduction

The role of inclusions in the fracture behaviour of steel is now out of doubt. The most recent research deals with the analysis of the different types of inclusions and their influence on the mechanical properties of steel ( Ånmark et al., 2015; Guo et al., 2018; Qiu et al., 2019). It is worth mentioning the studies focused on improving the deformability of fragile inclusions to ensure a good mechanical performance of the steel during the drawing process (Yan et al., 2014; Yan et al., 2019).
