The duplex stainless steels (UNS S32304) after solid solution annealing at two different temperature (1323K and 1573K) were subjected to the same cold rolling with ε =3 and subsequent annealing for 230 min at 1323 K . The corresponding interface character distribution (ICD) were determined by electron backscatter diffraction (EBSD). The results show that a larger population of phase boundaries (PB) having K-S orientation relationship (OR) between the neighboring δ and γ grains was introduced and therefore higher intergrannular corrosion resistance (ICR) were resulted in the specimen initially solid-solution annealed at 1573K.
