Impacting Fuelling Dynamics Towards Tunable Liquid Metal Machine

open access: yesExploration, EarlyView.
Confining liquid metal machines (LMMs) within one‐dimensional semi‐open channels reveals sustained, tuneable reciprocating dynamics, driven by fuel region evolution and boundary interactions. This work elucidates how spatial confinement and obstacle materials regulate symmetry‐breaking and directional control, enabling predictable LMM operation and ...

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

open access: yesMaterials 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

open access: yesMaterials 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

open access: yesMaterials 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 ...

Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

open access: yesMaterials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility

Corrosion Analysis of Rapidly Solidified and Subsequently Aged Al‐Ni and Al‐Fe‐Ni Alloys

open access: yesMaterials and Corrosion, EarlyView.
Fe addition modifies intermetallic phase chemistry and microgalvanic interactions in Al‐Ni alloys, shifting corrosion from generalized dissolution to localized attack. ABSTRACT This study investigates the influence of Fe addition and heat treatment on the corrosion behavior of Al–5 wt.%Ni and Al–2 wt.%Fe–1.5 wt.%Ni alloys, with particular emphasis on ...
