Effect of aluminum content on dislocation loops in model FeCrAl alloys

Nuclear Materials and Energy, 2019
Five kinds of iron-chromium-aluminum (FeCrAl) alloy samples with different contents of aluminum (Al)—Fe-12Cr, Fe-12Cr-2Al, Fe-12Cr-4Al, Fe-12Cr-6Al, and Fe-12Cr-8Al—were designed and prepared. All samples were then irradiated with 200 keV argon ions (Ar2+

Discontinous and continuous dynamic recrystallization of Fe-12.5Cr–4Al–2Mo-0.03Nb-0.08Y alloy during hot deformation

Journal of Materials Research and Technology
The hot deformation behavior and microstructure of Fe-12.5Cr–4Al–2Mo-0.03Nb-0.08Y alloy were studied under conditions of 800 °C–1200 °C/0.01 s−1∼10 s−1 using a combination of hot compression experiments, EBSD and TEM characterization.

Overlay welding of FeCrAl alloys

, 2016
I detta examensarbete har olika påsvetsningsmetoder som är lämpliga för en pannapplikation undersökts. Syftet med denna studie var att undersöka både för- och nackdelar med påsvetsningsmetoderna och föreslå några utvärderingskriterier på vissa kommersiella och experimentella legeringar som lämpar sig för påsvetsningsmaterial.

Controlled Growth of α-Al₂O₃ Nanofilm on FeCrAl Alloy as an Effective Cr Barrier for Solid Oxide Fuel Cell (SOFC) Cathode Air Pre-Heaters

Energies
Solid oxide fuel cell (SOFC) systems often employ metallic cathode air pre-heaters (CAPHs), frequently made from alloys with high chromium (Cr) content, to recover thermal energy from exhaust gases and pre-heat incoming air and fuel.

Effects of Nb–Ti double microalloying on the grain structure and precipitates of hot compressed FeCrAl alloys

Journal of Materials Research and Technology
Grain coarsening significantly weakens the strength and toughness of FeCrAl alloys at high temperatures. This study focused on the grain refinement behaviour of a Nb–Ti double-microalloyed FeCrAl alloy (Fe–18Cr–6Al‒0.2Ti‒0.2Nb) after hot compression, and
