“…During the drawing metal is in the conditions of complex non-monotonic loading, which is accompanied by intensive strain-hardening and grain flow creation [13,14]. Besides, the authors [15][16][17][18] point to the necessity to take into account and predict residual stresses in the wire after drawing.…”

The obtained phenomenological model of hardening G3Si1 and Sb08-G2S low-carbon welding wire during multistage drawing establishes the dependence of the hardening curve coefficients (hardening index and hardening modulus) on the integral tensile strain. The obtained model makes it possible to calculate the hardening curve, strength, and plasticity indicators of metal products based on the results of wire rod testing in the delivery state.

“…Cold forming processes such as cold rolling [1,2,3], cold drawing [4,5], cold extrusion [6,7] are metal fabrication techniques in which metals are shaped below their recrystallization temperature. As the amount of plastic deformation increases during cold forming, the strength and hardness of the formed metal parts increases while its ductility and toughness decrease.…”

The effects of twist angle and twist rate during the pre-torsional deformation on tensile and hardness properties of hot-rolled SCM415 low-alloy steel were investigated. Hot-rolled SCM415 round tensile specimens were pre-torsioned using a free-end torsion machine to 36, 72, 144 and 288 degrees at 2 different twist rates of 0.1 and 30 rpm. As the angle and the rate of twist increased, yield strength and ultimate tensile strength increased with a tradeoff in a reduction in ductility. The relationship of true stress and true strain within the uniform plastic deformation were well described by a power law. The strength coefficient and strain hardening exponent obtained from the power-law curve fitting decreased with increasing twist angle and higher twist rate, suggesting that higher shear strain and shear strain rate led to a decrease in work hardening capacity. The local hardness after pre-torsional deformation showed a positive gradient from specimens’ centers to their surfaces along the radial direction. Also, the local hardness at the same radial position increased with the increasing angle and rate of twist. The average grain sizes were uniform along the radial direction and were comparable for all pre-torsional conditions. The strengthening mechanism via pre-torsional deformation of hot-rolled SCM415 was shown to be dominated by the strain hardening effect. HIGHLIGHTS The effects of twist angle and twist rate during the pre-torsional deformation using a free-end torsion tester on tensile and hardness properties of hot-rolled SCM415 low-alloy steel were investigated Within uniform plastic deformation region, the power-law parameters, namely strength coefficient (K) and strain hardening exponent (n) decreased with increasing amount of shear plastic strain and shear strain rate during the pre-torsional deformation Local Vicker hardness showed a positive gradient from the central region to the surface of pre-torsioned specimens, and the local hardness at the same distance from the center increased with increasing torsional angle and twist rate The average grain sizes of pre-torsioned specimens were found to be unaffected by the amount of torsional angle or the rate of twist The strengthening of hot-rolled SCM415 steel via pre-torsional deformation is predominated by strain hardening effect GRAPHICAL ABSTRACT

Cold tube drawing is a metal forming process that enable to manufacturers to produce high precision tubes. The dimensions of the tube are reduced by drawing it through a conical converging die with or without inner tool. There are four types of tube cold drawing process. Their difference relies on the technique used for inner diameter calibration. Therefore, the main objective was determining the difference in development of crystallographic texture and stress-strain state between drawing with the fixed plug and hollow sinking process. The input feedstock (with E235 steel grade) after the recrystallizing anneal was cold drawn (drawing with the fixed plug, hollow sinking) by one drawing passes. Electron BackScatter Diffraction (EBSD) analysis was used to evaluate the changes of grain structure and texture connected with tubes manufacturing. The stress-strain state in the tube material during drawing was calculated using DEFORM-3D software and the crystallographic orientation with respect to the cylindrical reference frame (Z-direction = drawing direction). A significant difference in stress-strain state between drawing with the fixed plug and hollow sinking process was recorded in radial direction.
