“…In order to characterize and calibrate these key techniques, a number of specimens that have intergranular cracks with mechanical, microstructural, and electrochemical characteristics similar to those found in the field are needed. Recently, an advanced technique was developed for the controlled production of simulated IGSCC mock-ups that possess the mechanical and microstructural features comparable to service-induced cracks in alloy 600 SG tubing, which usually has relatively thin walls [14]. In this study, the above technique is extended to relatively thick forged nickel alloy components, including the alloy 600 base and alloy 182 weld metals of PZR nozzles.…”
