Abstract (EN)
An important objective of the deformation processing of metals is the production of defect free parts, with the desired properties. This goal can achieved through better design and by better control of the parameters of the deformation processes. In this study, we describe the tensile tests experience with cold forming of bolts at ambient temperatures. Next have been compared using different constitutive equations. Hollomon relationship provides the best fit of the data for 7 different (QSt32-3, 20MnB4 (a), 20MnB4 (b), 30MnB3, 41Cr4, 42CrMo4, 22BCr3) cold forging steels.
