EXPERIMENTAL AND NUMERICAL ASPECTS REGARDING HOT FORMABILITY OF MILD CARBON STEEL

Mariana POP, Dan FRUNZA, Adriana NEAG

Abstract


In order to understand the deformation of mild steel during hot plastic deformation, compressive tests at different elevated temperatures were achieved. Using compression tests the behavior of C22 steel were studied in 700-1000 0 C temperature range. Following the experiments performed, flow curves were drawn which reflect the influence of the deformation temperature on the flow stress. The influence of temperature on the non-uniformity of deformations was also established. By using the Forge simulation software, the variation of the deformation process parameters was highlighted (temperature, deformations, stresses, Latham-Cockroft breaking criterion).
