A new methodology is developed for the prediction of RPV embrittlement that utilizes a combination of domain models and nonlinear estimators including neural networks and nearest neighbor regressions. The Power Reactor Embrittlement Database is used in this study. The results from newly developed nearest neighbor projective fuser indicate that the combined embrittlement predictor achieved about...

Metallic materials will continue to have challenges related fracture, transcrystalline, and hydrogen embrittlement corrosion due severe area of application that is unavoidable. The study into the performance metallic has shown mechanism through stress cracking often occurs vis-viz electrochemical reduction reaction. phase diagram important solve problems hot corrosion, embrittlement, intergranu...

Hydrogen uptake in steel structures can cause a degradation mechanical properties such as toughness, and induce cracks. This phenomenon is widely known hydrogen embrittlement. For structural steels subjected to cathodic protection or pipelines transporting high-pressure gas, embrittlement represents an important challenge. Charpy V-notch testing provides fast inexpensive method for quantifying ...
