Abstract The supercritical CO 2 (S-CO 2) Brayton cycle has drawn much attention in the field
of thermal cycles due to its merits of high efficiency, simple layout and compact …

The supercritical carbon dioxide Brayton cycle is a promising power conversion option for
green energies, such as solar power and nuclear reactors. The material challenge is a …

Abstract Direct supercritical CO 2 (sCO 2) power cycles require structural materials
compatible with hot sCO 2 containing high levels of water and oxygen impurities. Chromia …

It is generally believed that when a chromia scale forms in high-temperature CO 2
environments, carbon uptake of alloys is nearly eliminated, thereby preventing carburization …

The characteristics of the corrosion products on scratched T92, TP347HFG, and IN625 in a
closed-loop and flowing supercritical CO 2 at 600° C were investigated. Severe exfoliation of …

Supercritical carbon dioxide (S-CO2) has the advantages of amphoteric liquid and gas,
which possesses many unique characteristics, such as good compressibility, high density …

Current and future power systems require steels resistant to high-temperature oxidation in
CO 2-rich environments. The introduction of structural defects by various surface treatments …

Past and current gas-cooled nuclear reactors rely on CO2-rich gases as a coolant to transfer
heat from the reactor core, while future reactors may utilize supercritical CO2 Brayton cycle …

The corrosion resistance of structural alloys was investigated in conditions that simulate
