图8 再结晶高纯Al在500℃保温期间具有<111>/θ取向差晶界再取向形成{111}/{111}近奇异晶界离线原位OIM及重叠极图迹线分析

Fig.8 Off-line in situ orientation imaging microscopies and grain boundary trace analyses showing the formation of the {111}/{111} near singular boundaries by the re-orientation of the grain boundaries having <111>/θ misorientation in the high purity aluminum heated at 500oC (a-c) re-orientation of the boundary between grain 1 and grain 6 at 1 min (a), 2 min (b), and 5 min (c), respectively (e-g) re-orientation of the boundary between grain 15 and grain 20 at 1 min (e), 4 min (f), and 6 min (g), respectively (i-k) re-orientation of the boundary between grain 23 and grain 29 at 0 min (i), 1 min (j), and 4 min (k), respectively (d, h, l) overlapped {111} pole figures of grain 1 and grain 6 in Fig.8c (d), grain 15 and grain 20 in Fig.8g (h), and grain 23 and grain 29 in Fig.8k (l), respectively (Blue and red GB traces are the GB positions before and after re-orientation, respectively, showing all the GB trace normals are passing through the overlapped {111} poles after GB re-orientation, indicating they have {111}/{111} GBICs)
