In the present paper the results of secondary phases determination and quantification in ZERON100 duplex steel, heat treated at 850-1000°C for 180-2400 s, are presented. During the isothermal heat treatments, at 850°C, the χ phase is the only phase to precipitate at α/γ boundaries and triple points, while at 900 and 950°C, χ phase is the first phase to precipitate after 180 s, followed by σ phase 300 s later. At all the temperatures the total amount of secondary phases is ∼3% after ,600 s aging. (17 refs.
