Hot Deformation Behaviour of Steel C45 at High Strains
Original language description
The hot stress-strain curves of the steel C45 were investigated by uniaxial compression tests within a wide strain range (up to 1.0). The unique computing method was developed which enabled to correct the shape of the experimentally obtained stress-strain curves, influenced by the samples? spreading at high strains. The value of the activation energy at hot forming was calculated (290 kJ.mol-1) using the peak stress values and the dynamic recrystallization kinetics was described. The mathematical modelwas developed which considered the predicted peak strains and described mathematically the influence of strain, strain rate and temperature on the flow stress. Reliability of this model was verified in comparison with the experimental data and compared with the stress-strain curves calculated according to the software FORGE material database. Thanks to its physical fundamentals the developed model is more accurate than the FORGE-based calculations, at the highest strain rates in particul
