Abstract
Enhancing the mechanical properties of products by developing new technologically advanced SPD methods, as the most efficient for strengthening of materials due to deep refinement of the initial structure, is an urgent task. For this purpose, a method was developed for the continuous forming of threaded rods with the required properties, using successive operations of rolling and transverse shear. The produced rods with a threaded profile can be used in construction as reinforcing bars for the reinforcement of concrete structures. The studies were conducted using mathematical modeling and physical experiments. We analyzed the stress-strain state of the produced billets. In one processing cycle, the strength of the initial billet from low-carbon steel 10 was raised from 350 to 530-550 MPa and simultaneously a threaded profile was formed. The obtained parameters comply with the Russian state standard GOST for steel reinforcing bars of the A500 class used in construction.
