Electrochemical hydrogen charging to simulate hydrogen flaking in pressure vessel steels [PDF]
Engineering Fracture Mechanics, 2019 The current study investigates hydrogen flaking in large forgings. Two industrially forged pressure vessel materials, exhibiting different segregation behavior are compared for this purpose. Electrochemical hydrogen charging is used to simulate the flakes, present in real-life applications, on a small scale. As such, the sensitivity of the materials to
