..., there is still no clear image to describe how the impurities affect corrosion due to very limited database and some controversial results. More importantly, there is a serious concern on the stress corrosion cracking (SCC) susceptibility of the pipeline because of the presence of corrosive agents and high...

The susceptibility to hydrogen embrittlement was investigated on different build orientations of AM 718 by slow strain rate (SSR) testing and static crack growth rate (SCGR) testing in 3.5 wt.% NaCl under cathodic protection. The susceptibility of AM 718 to hydrogen...
