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 …

Both indirect‐and direct‐fired supercritical CO2 cycles for high‐efficiency power generation
are expected to have impurities that may greatly alter the compatibility of Fe‐and Ni‐based …

Abstract Model alloys Fe-20Cr-2Mn and Fe-20Cr-20Ni-2Mn (wt.%) were exposed to Ar-
20CO 2-(20H 2 O) gases at 650° C. Oxide formation was affected by alloy Mn diffusion …

Abstract Model alloys Fe–9Cr, Fe–20Cr and Fe-20Cr–20Ni (wt.%) with 0.1% Ce or 2% Mn
were exposed to Ar–20CO 2 and Ar–20CO 2–20H 2 O gas mixtures at 650° C. Ferritic alloys …

Future CO 2 based power systems require steels resistant to corrosion in high-temperature
CO 2-rich environments. Candidate 9Cr ferritic-martensitic steels degrade by surface …

The petrochemical industry is implementing practices to recover flue gases to reduce energy
waste. H 2 S in the recovered gas makes the gaseous environment acidic during reuse. This …

Abstract Model alloys Fe-9Cr, Fe-20Cr (wt.%) and these alloys doped with 2% Mn or 0.5% Si
were exposed to Ar-20% CO 2-20% H 2 O-(0, 0.5)% SO 2 (vol.%) gas at 811° C for up to 500 …

Abstract Model alloys Ni-(20, 30) Cr (wt.%) with (0.1, 1)% Si, 1.5% Al or (1, 2)% Ti were
exposed to Ar-20CO 2 at 700° C. Samples were electropolished before reaction to avoid …

Interpreting high-temperature corrosion induced by mixed-gas atmospheres is challenging
due to the different contributions of oxidizing gases. Here, a comprehensive study on the …

Abstract Model alloys, Fe–9Cr, Fe–9Cr–2Mn and Fe–9Cr–0.5 Si (wt%) were exposed to Ar–
20% CO 2–20% H 2 O–(0, 0.1, 0.5 and 1.0%) SO 2 gases at 650° C. In the absence of SO 2 …
