Autor: Zhiwei Gao, Shipin Wu, Ting Xiang, Baoming Gong, Caiyan Deng

Publikováno v: Journal of Materials Research and Technology, Vol 31, Iss , Pp 2646-2657 (2024)

The influence of post-weld heat treatment (PWHT) and fatigue damage on the hydrogen embrittlement sensitivity of X80 steel welded joints, obtained using flux-cored arc welding method, was investigated in the study. Compared to the as-welded specimens

Investigation of properties of epoxy coating on X80 steelunder cathodic polarization conditions

Autor: Lyudmila Nyrkova

Publikováno v: Zaštita Materijala, Vol 65, Iss 2, Pp 273-278 (2024)

The effect of cathodic polarization on the properties of the protective epoxy coating on X80 steel samples under cyclic changes in temperature from 20 to 75 оC over a period ~3.5 months was investigated. It is shown that in a 3% NaCl solution, with

Surface Residual Stresses Evolution in API 5L X80 Steel with Different Surface Finish under Tensile Monotonic Loads

Autor: Raphael José Elino da Silveira, Guilherme Zeemann Pinho Emygdio, Juan Manuel Pardal, Leosdan Figueredo Noris, Maria Cindra Fonseca

Publikováno v: Materials Research, Vol 27 (2024)

Residual stresses exist intrinsically in any manufactured or processed material, significantly influencing its mechanical properties. Shot peening enhances fatigue life by introducing compressive residual stresses at the surface, however, the benefic
