Microstructural Evolution of UNS S32205 Duplex Stainless Steel During Cold Rolling and Subsequent Annealing. Materials Research, 28. https://doi.org/10.1590/1980-5373-MR-2024-02761516-1439https://hdl.handle.net/10289/17417We followed the microstructural evolution of UNS S32205 duplex stainless steel during cold rolling up to 79% reduction in thickness and at early stages of isothermal annealing at 1080ºC. Qualitative analysis of peak broadening and kernel average misorientation (KAM) parameter obtained by X-ray diffraction (XRD) and electron backscatter diffraction (EBSD), respectively, indicated a higher work hardening of austenite. Strain-induced martensite was not detected within this strain range by using X-ray diffraction and DC-magnetisation measurements. Two particular rolling thickness reductions were chosen for recrystallisation studies; i.e., 43% and 64%. After annealing for 1 min, primary recrystallisation occurred in ferrite (42% of recrystallised grains for 43% cold rolling), whereas austenite only recovered. For a reduction of 64%, the recrystallised fraction of ferrite did not change significantly, while austenite reached a recrystallised fraction of 43%. Full recrystallisation is noticed after annealing for 3 min for both conditions resulting in a bamboo-like grain structure.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/duplex stainless steelUNS S32205peak broadening analysisRecrystallisationTextureEBSDJournal Article10.1590/1980-5373-MR-2024-02761980-537340 Engineering4016 Materials Engineering4016 Materials engineering4017 Mechanical engineering
