In order to realize numerical simulation of hot rolling and establish the hot deformation process parameters for X80 pipeline steel, the flow stress behavior of X80 pipeline steel during hot deformation was investigated in the temperature range of 900-1100°C and strain rate of 0.01-1s-1 on Gleeble-3500 thermo-simulation machine. The results show that dynamic recover and dynamic recrystallization occur...
