Abstract

n SEM by investigated was steel pipeline X70 5L API an of section cross and surface the, research this In hydrogen electrochemical the, Then. inclusions of morphology and type determine to order in analysis EDS and hydrogen create to utilized was thiocyanate ammonium l/g 3 and acid sulfuric M 2.0 using technique charging charged hydrogen of section cross the, experiments charging hydrogen After. steel X70 in) HICs (cracks induced initiation crack HIC The. cracks HIC find to solution nital% 2 with etched then µm 1 to up polished was steels Diffraction Backscatter Electron and) EDS (Spectroscopy Dispersive Energy by studied was propagation and and sulfide, oxide including inclusions of types various are there that showed results The. techniques) EBSD( was inclusions of accumulation the, however; steel X70 received-as of section cross the at inclusions nitride special some only, specimens charged hydrogen in, But. regions other in than section cross of center the at higher precipices and inclusions Oxide. cracks HIC initiate can, inclusions type nitride and sulfide as such, inclusions .steel X70 of toughness fracture the reduce they but, propagation and initiation crack HIC in role any not has Other. texture random or weak with area an in initiates crack the that showed results EBSD the, Moreover .discussed was, crack HIC with involved grains of orientation as such, growth crack in parameters effec
