At present time tendencies in the development of engineering and technologies in the manufacturing the metal ware need the effective complex impact on material microstructure by methods of different nature. Special attention should be paid to the combined processes of deformational treatment which are constructed on such basic operations as drawing, rolling, pressing, etc. Despite a plenty of studies and high efficiency of combined methods the problem of understanding the scientific grounds for choice the processing parameters which ensure the guaranteed level and high stability of metals and alloys properties has not been solved jet. Medium carbon steel is used for a wide range of metal ware products. Medium carbon steel wire with 0.5 %C was chosen for the experiments. It was subjected to different kinds of deformational processing such as tensile deformation, alternating bending, twisting and their combination. Complex of experimental research was carried out in order to study the influence of different kinds of plastic deformation on the medium carbon steel wire microstructure. By scanning electron-microscope analysis the peculiarities of pearlite behavior after deformational processing with different total deformation degree were studied. The comparative analysis of cementite changing after different kinds of deformation was conducted.

This study focuses on the evolution in the microstructure, texture and mechanical properties of medium carbon steel wires obtained by wire drawing at Tréfissoud Company for the manufacturing of the spring mattress. Wire drawing induces elongation of grains in the direction of drawing with the development of the <110> fibre texture parallel to the wire axis. Kinking and bending of cementite lamellae were observed during the drawing process. The work was carried out respectively on three states, wire rod and drawn states for two different amounts (ε %=43,6 and 60 %), using the optical and SEM microscopy, electron backscatter diffraction and X-ray diffraction analysis for examination of the microstructure and texture evolution, the hardness Vickers and tensile test to follow the curing of the studied wires.
