摘要：

Duplex stainless steel UNS S31803 samples were cross-rolled with a true strain of ε = 2 followed by annealing at 1323 K for 2 min and 240 min, respectively. The distributions of intervariant boundary planes in the precipitated austenite(A) from ferrite(F) and phase boundary planes conforming to Kurdjumov-Sache(K-S) orientation relationship(OR) were characterized by electron backscatter diffraction(EBSD) and the five-para me ter analysis(FPA) method, respectively. The intervariant boundary planes with misorientation angle of 60° around <111 > and <011 > occur frequently and tend to terminate on the {111} plane. At the grain size level of 4 μm, the phase boundary appears to be connected with the K-S OR terminating on{110}F || {111}A at the early stage of annealing. When the grain size reaches approximately 20 μm, phase boundary was modified into {541}F||{533}A due to twinning in austenite during annealing.
