“…The material thermomechanical treatment significantly increases the corrosion resistance and strength parameters of metals and alloys. [42] Features of the cracking behavior of pipeline steel are studied in Ohaeri et al [43] The high-temperature annealing has both negative and positive results. The annealing leads to larger grains, which provide less defectiveness.…”

Studies on the effect of wall textures and crystallographic grain orientations on graphene coatings and water droplets wettability are conducted. To date, there is almost no data on the effect of surface textures and high‐temperature annealing on the wettability of the graphene‐coated copper. It is generally accepted that the water contact angle on the graphene‐coated copper with one graphene layer is ≈85°–86°. However, changing the annealing duration, and using different surface textures, it is possible to change the graphene wettability over a wide range of static droplet contact angles from 81° to 96°, which allows providing both hydrophilic and hydrophobic properties. With the growth of annealing duration, the average grain size increases from 0.1–1 to 10 mm and more. By changing the annealing duration and the surface roughness, it is possible to realize the grains orientation (001) and (111), as well as the simultaneous presence of different grains orientations. Molecular dynamic modeling of the influence of orientation and grain size on the wettability of the graphene coating is performed. The calculation results correspond to the experimental data on contact angles. The key factors affecting the wettability of graphene are presented and analyzed.

“…However, to the best of our knowledge, little work has been reported about the effect of hot rolling process on corrosion or SCC behavior of HSLA steels [25]. The work of Ohaeri et al [25] revealed that thermomechanical processing at different conditions could introduce crystallographic texture and resulted in corrosion-resistance variation. Hot rolling at a slightly higher temperature and faster cooling rate produced a higher intensity of corrosion-resistant < 111 >||ND-oriented grains and thereby better corrosion resistance [25].…”

The effect of hot rolling process on microstructure evolution, mechanical properties and stress corrosion cracking (SCC) resistance of high-strength low-alloy (HSLA) steels was investigated by varying the finish rolling temperature (FRT) and total rolling reduction. The results revealed granular bainite with large equiaxed grains was obtained by a total rolling reduction of 60% with the FRT of 950 °C (within recrystallization temperature T r ). The larger grain size and much less grain boundaries should account for the relatively lower strength and SCC resistance. A larger rolling reduction of 80% under the same FRT resulted in the formation of massive martensite-austenite (M/A) constituents and resultant low ductility and SCC resistance. In contrast, a good combination of strength, ductility and SCC resistance was obtained via 80% rolling reduction with the FRT of 860 °C (within non-recrystallization temperature T nr ), probably because of the fine grain size and M/A constituents, as well as a high density of grain boundary network.

“…Such an environment would easily result in severe CO 2 corrosion, which may reduce the service life of the pipeline and lead to the leakage of the pipeline [2]. Many studies so far have focused on corrosion of high-strength pipeline steels in oil and natural gas transportation environments [2][3][4][5][6][7][8][9][10][11].…”

An investigation into the electrochemical corrosion behavior of X80 pipeline steel under different elastic and plastic tensile stress in a CO2-saturated NaCl solution has been carried out by using open-circuit potential, potentiodynamic polarization, electrochemical impedance spectroscopy, and surface analysis techniques. The results show that the corrosion rate of X80 steel first increases and then slightly decreases with the increase of elastic tensile stress, whereas the corrosion rate sharply increases with the increase of plastic tensile stress. Both elastic and plastic tensile stress can enhance steel corrosion by improving the electrochemical activity of both anodic and cathodic reactions. Moreover, compared with elastic tensile stress, plastic tensile stress has a more significant effect. Furthermore, electrochemical reactions for CO2 corrosion and mechanoelectrochemical effect are used to reasonably explain the corrosion behavior of stressed X80 steel in CO2 environment.
