N2 - The microstructure of X80 steel pipes that we have developed for 'strain-based design' has been examined in relationship to chemical composition, heat treatment conditions and thermal aging behavior. The quantity of cementite precipitation adapts with the cooling conditions and affects the age hardening behavior. The amount of solute carbon would decrease as cementite precipitation progresses, resulting that the strain hardening, which is caused by the segregation of solute carbon atoms at dislocation lines, is restrained. The effect of chemical composition on the thermal aging behavior is also discussed from the viewpoint of strain hardening by interstitials.
