Interfacial boundary character distribution in cold-rolled and annealed duplex stainless steel
The duplex stainless steels after solid solution at different temperature were subjected to the same cold rolling and annealing for varied time at 1323 K.The interfacial boundary character distribution (IBCD) of the two groups of specimens was investigated using EBSD technology.The results indicate that significant numbers of phase boundaries (PBs) with specific ORs (K-S, N-W and Pitsch) and low-angle grain boundaries (LABs) in the α matrix and twin boundaries (TBs) in the γ precipitates were introduced in the cold-rolled and annealed specimens previously solid-solution treated at 1563K.In contrast, a quite different IBCD consisting of general PBs and high-angle grain boundaries (HABs) in the αdeveloped in the specimens previously solid-solution treated at 1323K.
