Untersuchungen über die transkristalline Spannungsrißkorrosion austenitischer Chrom‐Nickel‐Stähle in heißen Chloridlösungen

Abstract: Zur weiteren Aufklärung verschiedener Einzelheiten bei der transkristallinen Spannungsrißkorrosion austenitischer Cr‐Ni‐Stähle wurden Zugversuche mit dem Werkstoff X 5 Cr Ni 189 in heißen, hochkonzentrierten MgCl2‐Lösungen durchgeführt. Außenstromlose Versuche ergaben, daß die Spannungsabhängigkeit der Standzeit je nach den Versuchsbedingungen formal durch eine Potenz‐ oder Expotentialfunktion beschrieben werden kann. Bis zu Spannungen von 2 kp · mm−2 hinab war keine Grenze zu beobachten, unterhalb derer Spann… Show more

“…6 It has been reported that cracks are often created by the initiation and growth of corrosion pits in near-neutral pH and mild environments. 7,8 Because the susceptibility to SCC of sensitized stainless steels is closely related to pitting, it is important to elucidate the mechanism of pitting at the grain boundaries on sensitized stainless steels in detail. In this study, we focused on pit initiation at the sensitized grain boundaries in a 0.1 M NaCl solution.…”

“…The method of dividing the time-to-fracture into two stages on the basis of elongationtime curves has been used by Bleckmann et al (9), Kohl(10), Brauns et al (11), and Logan (12). These workers showed that during the induction period the elongation rate coincides with the creep rate of the alloy obtained in an inert environment and de- In the case of SCC tests at a fixed potential, the potentials were controlled by means of a potentiostat using a platinized-platinum gauze as the counter electrode.…”
