Effect of Re or W Addition on the Oxidation Behaviour of a Compositionally Complex Ta–Mo–Cr–Ti–Al Alloy in Air at 1000°C

open access: yesMaterials and Corrosion, EarlyView.
The effect of addition of 3 at.% of either Re or W on the oxidation performance of equimolar Ta–Mo–Cr–Ti–Al is investigated and found to be beneficial, at least temporarily. Additionally, the oxide (Ti,Ta)O2 has been identified and characterised as a main part of the oxide scale. ABSTRACT Presuming that doping of protective (Cr,Ta,Ti)O2 with cations of

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.
