The effects of microstructure on the mechanical properties of the high-carbon steel wires were investigated. The wires were fabricated with carbon content of 0.82 and 1.02 wt.% and drawing strain from 4.12 to 4.32. The bending fatigue resistance and torsion ductility were measured by a Hunter fatigue tester and a torsion tester specially designed for fine wires. As the carbon content and drawing strain increased, the fatigue resistance and the torsional ductility of the steel wires decreased, and the tensile strength increased. To elucidate the causes of these behaviors, the microstructure in terms of lamellar spacing (λP), cementite thickness (tC) and morphology of cementite was observed using transmission electron microscopy (TEM) and 3-dimensional atom probe (3-DAP).
