dc.description.abstract | This paper presents a new model for calculation of critical strain for initialization of dynamic recrystallization.
The new model reflects the history of forming in the deformation zone during rolling. In this region of restricted
deformation, the strain rate curve for the surface of the strip exhibits two peaks. These are the two reasons
why the onset of dynamic recrystallization DRX near the surface of the rolled part occurs later than in theory
during strip rolling. The present model had been used in a program for simulation of forming processes with
the aid of FEM and a comparison between the physical experiment and a mathematical model had been drawn. | en |

dc.description.abstract-en | Članak daje novi model za vrjednovanje kritične deformacije početka
dinamičke rekristalizacije. Novi model odražava razvoj oblikovanja pri valjanju, gdje utjecajem otežane deformacije,
krivulja deformacijske brzine na površinskom sloju ima dva ekstrema. To su dva razloga gdje je početak
dinamičke rekristalizacije blizu površine valjanog komada zakočen, protivno teoriji valjanja trake. Dati model je
bio primijenjen u programu pri simulaciji procesa oblikovanja metodom konačnih elemenata (MKE), a provedena
je i usporedba izmedju fizikalnog eksperimenta i matematičkog modela. | en |
