the main contribution of the present work is to investigate the capability of exponential-type constitutive equationto model the warm deformation flow curves of a eutectoid steel in the temperature range of 620-770 °c andat the strain rates in the range of 0.01-10 s-1 conducted on a gleeble-1500 thermomechanical simulator. warmdeformation in this temperature range facilitates the occurrence of ...

This study investigated the true stress (σ)–true strain (ε) relationship up to plastic deformation limit in ferrite–pearlite (FP) steel at various temperatures. We found that a decrease temperature resulted an increase lower yield strength (LYS) and tensile (TS), both uniform total elongations. When was increased from 673 773 K, TS elongations decreased due blue brittleness. In σ–ε of FP temper...
