| Abstract Scope |
To improve the durability of pearlitic steel wire manufactured through the wire drawing process, it is essential to understand the effect of microstructure on the deformation and fracture behavior of pearlite. The pearlitic steel wire is composed of a layered structure of ferrite and cementite, and in particular, the width and spacing of the cementite are very densely formed at the level of about 50 nm. In this study, a micro-pillar compression test was performed to experimentally observe the effect of microstructure on the deformation and fracture behavior of pearlitic steel wires. Based on the difference in hardness values measured by nanoindentation test, microstructures were classified into 5 types, and micro-pillars were prepared using FIB based on the classified microstructure. Meanwhile, finite element analysis was performed considering the fracture model for simulating effect of cementite on deformation and fracture behavior during compression of pearlitic steel in the form of micro-pillars. |
