Approach to obtaining medium carbon steel wire with a specified set of mechanical properties after combined deformational processing


Progressive development of metal ware manufacturing is closely connected with implementation of technologies with integrated or combined operations. Continuous method of wire deformational processing by drawing with bending and twisting was developed. Medium carbon steel wire with 0.5 %C was used for the experiments. The results of simulation in Deform-3D showed that distributions of tensile and compression stresses at combined deformational processing are uniform along the deformation zone. Microscopic analysis of the processed wire indicated that after combined deformational processing a homogeneous structure is formed in the medium carbon steel wire. After tensile test, it was proved that combination of drawing with bending and twisting allows ones to achieve the different combination of strength and ductile properties of medium carbon steel wire with one diameter and carbon content.
