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.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Multi‐Method Investigation of Intergranular Corrosion of the Aluminium Alloy EN AW‐2024 With Different Cooling Rates After Solution Heat Treatment—Metallography and Eddy Current Testing

Materials and Corrosion, EarlyView.
The corrosion resistance of heat‐treatable aluminium alloys depends directly on the applied heat treatment. This article discusses the relationship between cooling rate and intergranular corrosion sensitivity. The intergranular corrosion depths were determined by light microscopy of cross‐sections and correlated with both non‐destructive eddy current ...

Effect of Metal–Metal Distance on the Performance of Dual‐Atom Catalysts for the Oxygen Reduction Reaction: A Density Functional Theory and Micro‐kinetics Study

Small, EarlyView.
Density functional theory calculations and microkinetic modeling were carried out on 108 dual‐atom catalysts with varied metalmetal distances ranging from 2.2 to 3.5 Å. The results reveal that moderate spacing of around 3.0 Å promotes bridging oxygen adsorption and dissociative reduction pathways, weakens the hydroxylhydroperoxyl scaling relationship ...

Buried Liquid Metal Interfaces: Oxides and Surface Water‐Driven Hydrogen Bubbles

Small, EarlyView.
When liquid metal (EGaIn) is injected against substrates, its native oxide deposits at the buried interface via a tank‐tread mechanism. On glass (insulating) substrates, liquid metal reacts with surface water to generate hydrogen bubbles, with bubble size and density governed by humidity and surface hydrophilicity.
