dc.description.abstractFerrite-austenite duplex stainless steels (DSS) are replacing austenitic stainless steels in many applications due to its high mechanical and corrosion resistance. However, magnetic measurements of ferrite volume fraction using a ferritscope of cold worked samples indicate a reduction in the ferrite content with increasing mechanical work. Considering this fact, this work studies the influence of the cold working on the ferrite/austenite ratio. Samples of UNS S31803 DSS sheet, originally 3 mm thick, were solution-treated at 1175°C for 30 minutes and water quenched; after that, different levels of cold working were applied. Ferrite volume fraction was determined using two distinct methods: quantitative stereology with an optical microscope and magnetic measurements using a ferritscope; a detailed microstructural characterization, including X-ray diffractometry, was conducted to base the discussion of a possible ferrite-to-austenite diffusionless transformation.
