... on the reproducibility of tests carried out in weld joints due to different fracture susceptibility and film formation ability of the weld joint regions. It was observed that the loss of ductility and the iron sulphide film morphology, and the promoted barrier effect against hydrogen, are dependent on the weld joint...

.... Historically, the slow strain rate (SSR) test technique has been the main method used to evaluate the susceptibility of the carbon steel liner(s) to SCC. Recently, cyclic crack growth rate (CGR) testing has been used to complement the SSR test technique to evaluate SCC susceptibility. A test program...

... ABSTRACT Two commonly used aluminum alloys, namely 5083 and 6061, in fabrication of Aluminum Plate Heat Exchangers (APHE) were tested under four-point bending at different volumes of mercury and stress to measure their susceptibility to liquid metal embrittlement (LME) by mercury. The test...

... behavior suggests that the 725 exhibited the highest susceptibility, while 955 and 945X appeared to exhibit similar fatigue crack growth rate behavior. A static crack growth rate of 10 -6 mm/s (under constant K conditions) was obtained at 50ksivin (55MPavm) on 725, while it required K values of about...
