... in the manner shown in Figure 5, and metallographic examination was conducted on the cross section to look for evidence of cracking, stress accelerated corrosion and/or roughening of the surface. Following exposure to the bio-oils, the carbon steel and 2¼ Cr-1 Mo samples were observed to have the largest amount...

... ABSTRACT Most pipelines are exposed to severe operational conditions and sour environments that might lead to hydrogen entry in steels. The existence of weld joints can affect the service life of these tubes, acting as preferential areas for incidence of hydrogen embrittlement, due...

... ABSTRACT Stress corrosion cracking (SCC) is a documented threat to the integrity of the radioactive waste storage tanks at Hanford. An extensive amount of time and effort has been spent investigating the chemistry limits of the waste necessary to prevent SCC of the carbon steel tanks...

... reducing the service life of these alloys. The objective of this study was to determine whether the surface roughness of an alloy has a significant effect on its corrosion resistance in the presence of microorganisms.
