A new combined deformation technology combining radial-shear broaching and drawing technology is developed in this work, which makes it possible to improve the mechanical and operational properties of carbon-steel bars. As a result, during three straining cycles, the average value of microhardness in the central zone is of 2085 MPa, in the neutral zone, it is of 2505 MPa, and in the surface zone, it is of 2915 MPa. In addition, the strength properties are increased by almost 2 times, the plastic characteristics are reduced not much, but remain at a fairly good level for steel 45 due to obtaining gradient microstructure during straining.

Key words: steel, bar, drawing, radial-shear broaching, severe plastic deformation.
