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
