Abstract During cold-drawing of plain steel wires, the fine lamellar cementitealtered into a ductile phase with feasible deformability. A lot of ledges, which mayemit the dislocations, are found along the Fe_3C/Fe interface. This seems to be oneof the causes for formation of greater dislocation density along the Fe_3C/Fe inter-face during deformation. There was enough evidence to prove that the dislocationcut through Fe_3C. Therefore, it is necessary to consider its effect on strengthening.
