摘要

The thermal simulation experiments of X80 pipeline steel were performed using Gleeble 1500 thermomechanical simulator. The controlled rolling and controlled cooling experiments were used to investigate the effect of cooling rate on the microstructures and mechanical properties of X80 pipeline steel. The results show that the cooling rate plays an important role in the ferrite grain size and the volume fraction of granular bainite. In order to obtain good comprehensive mechanical properties, it is necessary that the cooling rate should be 12～20°C/s.
