Assessment of Structure Integrity and Mechanical Properties of Carbon Steel Wire in Combined Deformation Processing

Abstract:

Because basic metal forming methods have reached the maximum of their manufacturing capabilities in deformation-velocity processing modes so called combined or integrated processing methods move to the forefront. The method of combined deformation processing based on drawing with bending and torsion deformation was developed. On the example of carbon steel wire it was shown that microstructure and mechanical properties can vary in a wide range depending on the process regimes. In order to estimate the probability of carbon steel wire fracture at the designed combined deformation processing the simulation complex DEFORM-3D was used. The results demonstrate that there are no areas with high concentrations of hydrostatic pressure and overestimated values Cockcroft-Latham criterion. For the developed combined deformation processing of wire by drawing with alternating bending and torsion, algorithm for the prediction of carbon steel wire microstructure and mechanical properties changing at combined deformation processing was carried out. The developed methodological approach to forecasting of formation of the structure and mechanical properties during combined deformation processing of carbon steel can be used to solve both direct and inverse problems.
