SH-CCT of High-Strain Pipeline Steel X80

Abstract:

Simulated heat affected zone continuous cooling transformation curve was measured by means of Gleeble 3500 thermal simulator. According to the results of microstructure observation and hardness measurement, influence of cooling rates on the microstructure and hardness in coarse grain zone of high-strain pipeline steel X80 was studied. The results illustrated that softening in coarse grain zone was ubiquitous problem for high-strain pipeline steel X80. There were mainly four types of phase transformation in coarse grain zone of high-strain pipeline steel X80. Polygonal ferrite(PF) and a small quantity of pearlite, granular bainite, bath bainite and bath martensite were obtained after different cooling time.
