The work performed under this investigation included (1) acquisition of pipeline specimens recovered from service that exhibit stress corrosion cracking damage, (2) characterization of the mechanical driving force for crack propagation with fracture surface topography analysis (FRASTA), (3) analysis of the effect of gas pressure on the crack opening geometry with finite element modeling (FEM), (4) chemical characterization of the corrosion deposits on fracture surfaces with surface analysis by laser ionization (SALI) and x-ray photoelectron spectroscopy (XPS), and (5) characterization of stress corrosion cracking susceptibility by AC impedance spectroscopy. The approach taken in each facet of this investigation is described below. When specialized experimental techniques were involved (FRASTA, SALI, and XPS), brief summaries of the concept supporting these experimental techniques are provided.
