Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit

Materials and Corrosion, EarlyView.
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Corrosion Behavior of Commercial FeCrAl and TiAl Alloys in Molten Pb With 2E‐7 wt% Oxygen at 600°C and 700°C

Materials and Corrosion, EarlyView.
Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.
