摘      要：The static recrystallization process of a cold-rolled Mg-Zn-Gd alloy was tracked by a quasi-in-situ electron backscatter diffraction method to investigate the orientations of *** results show that orientation distribution of nuclei is associated with nucleation *** continuous static recrystallization nuclei display similar orientations to the parent grains with TD ***,discontinuous static recrystallization nuclei formed within the parent grains(TD-45~0 orientation) show random orientations and a variety of misorientation angles but preferred axes or .Interestingly,a special oriented nucleation is *** static recrystallization nuclei originated from boundaries of the parent grain(TD-70° orientation) show concentrated TD orientations in another side due to the preferred misorientation relationship 70°(∑18 b).It is speculated that these two special misorientation relationships are related to the dislocation type.
