Features of work hardening of Kh18N10T steel under conditions of cold electrostimulated drawing

The results of experimental investigation of the evolution of the structure and mechanical properties of Kh18N10T steel wire subjected to normal and electrostimulated drawing at a rate of 1.88 m/sec and a total reduction of up to 75% are given. The change in yield and tensile strengths, elongation, and reduction in electrostimulated drawing characterizing the higher plasticity of the material is analyzed. The structural changes accompanying the process of electrostimulated drawing include a difference in the character of the layer work hardened in drawing, evolution of the substructure, and the appearance of re crystallization twins.
