- W2354495602 abstract "The simulated heat-affected zone continuous cooling transformation curve(SH-CCT curve) of X80 pipeline weld heat affected zone was made by Gleeble 3500.By the metallographic analysis,microhardness measurement and charpy impact test,the rules of phase transformation and properties change of X80 pipeline weld coarse-grain region at different cooling rate were investigated.The results show that when cooling rate is lower than 0.3℃/s,the microstructure of coarse-grain region is the combination of coarse polygonal ferrite and a small amount of pearlite or granular bainite,and the impact toughness is good but the hardness is low.When cooling rate is between 0.3℃/s and 2℃/s,the granular bainite and MA island structure increase,the grain boundary is dim and the impact toughness is bad.When cooling rates is between 2℃/s and 30℃/s,the main microstructure of the X80 pipeline weld heat affected zone is granular bainite,the shape and distribution of MA island structure were uniform,and the impact toughness is excellent.When cooling rates is faster than 30℃ /s,the content of the granular bainite decreases with the increase of cooling rate,while the content of bainite ferrite increases gradually,the hardness increases and the impact toughness decreases." @default.
