| Abstract: | The effects of deformation temperature in ferrite and austenite zones,stress rote and cooling rote on the mechanical properties of X60 pipeline steel were investigated by adjusting austenite-ferrite-repeating deformation parameters. The results of the study indicate that the mechanical properties of X60 pipeline steel are enhanced by this method. |
