Abstract

Three techniques for ferrite quantification were applied in a duplex stainless steel UNS S31803 solution treated at three different temperatures, 1000, 1100 and 1200°C, in order to verify their compliance with the results from ThermoCalc® prediction. It is verified that only austenite and ferrite phases are present in the samples and that an increasing in solution treatment temperature led to the increase of the volume fraction of ferrite. It is also observed that quantitative stereology technique shows absolute values closer to ThermoCalc® predictions. On the other hand, measurements by ferritoscope and XRD show significant deviations, probably due to texturing effect imposed by the rolling process.
