摘要

不均匀氧化鳞是高温腐蚀中的一种常见现象，但其形成机理尚未完全揭示。我们对一种在 650°C/15 MPa SC-CO2 中具有优异耐腐蚀性能的新型氧化铝奥氏体（AFA）不锈钢进行了系统研究。研究表明，不均匀氧化物的形成是由于 AFA 钢的再结晶行为对其微观结构演变和随后的腐蚀行为产生了重大影响。与薄氧化皮相比，厚氧化皮是由于延迟再结晶导致基体位错和晶界密度相对较高，从而促进了离子的快速向外扩散。

New insight on the formation of uneven oxide scales on AFA steel in supercritical CO2: Roles of recrystallization degree on the high temperature corrosion resistance

Uneven oxide scale is a common phenomenon in high-temperature corrosion, but the formation mechanism has not been fully uncovered. A new alumina-forming austenitic (AFA) stainless steel with superior corrosion resistance in 650°C/15 MPa SC-CO₂, has been systematically investigated. It is demonstrated that the uneven oxide was formed by the significant impact of the recrystallization behavior of AFA steel on its microstructural evolution and subsequent corrosion behavior. Compared with the thin oxide scale, the thick oxide scale was caused by the relatively higher density of dislocations and grain boundaries of matrix resulting from delayed recrystallization, which facilitated the rapid outward diffusion of ions.
