“…The activated slip systems in the DBs in the present sample are different from those in the SBSS in the tensile-deformed aluminum single crystal with the same orientation in which the slip on the P2 plane is activated. [10][11][12][13][14] In addition, the slip pattern in the DBs in the present sample looks similar to that observed in kink bands. 18) Figures 4(c) and 4(d) are the h001i pole figures constructed from the EBSD data measured in an area of 208 Â 285 mm 2 in regions I and II, respectively.…”

In order to study the formation of deformation bands (DBs) and its relation to recrystallization, an aluminum single crystal was compressed along the h011i direction and subsequently annealed. In the present crystal, the four slip systems having the largest Schmid factors were on two slip planes that were symmetrically arranged with respect to the direction of observation. The overall deformation was consistent with the arrangement of these two major slip planes. In the central region of the observed surface, the major slip planes were activated to form a doubleslip pattern. On the other hand, at the corner regions, many DBs were formed. After annealing, recrystallization occurred in the regions containing the DBs. Recrystallized grains had a h111i-rotation relationship with the DBs. The experimental results were compared with those in tensile-deformed aluminum single crystals having the same crystallographic orientation.

“…[10][11][12][13][14] Although four slip systems on two slip planes have the largest Schmid factors, the activities of the two slip planes are not equal. Upon tensile deformation, the slip systems on one of the two slip planes are activated as the primary slip.…”

“…[1][2][3] Inoko and coworkers [4][5][6][7][8][9][10][11][12][13][14] have long been studying the deformation and recrystallization of tensile-deformed aluminum single crystals and bicrystals. They have recently found close correlation among slip morphology, cell structure, workhardening and recrystallization behavior of aluminum single crystals tensile-deformed along h001i, h111i or h112i direction in which macroscopic deformation was uniform without the formation of deformation bands due to the balanced activation of multiple slip from the initial stage of plastic deformation.…”

Deformation and recrystallization of 17%-and 34%-rolled aluminum single crystals of cube orientation were studied. Most slip bands observed in the TD surface were straight and the occurrences of cross-slip were small. There was a relatively large orientation variation in the TD surface and the deviation from the initial orientation reached 10 in the 34%-rolled sample. After annealing, recrystallized grains were formed both at the rolled surfaces and around the middle of the thickness of the sample. Two thirds of the recrystallized grains had h111i-rotation relationships with the deformed matrix. Although all h111i-rotation relationships were found, their occurrences were not the same. Above results are compared with those obtained in tensile-deformed aluminum single crystals with the same initial orientation.

“…On tensile deformation of h011i aluminum single specimens Kashihara et al 14,15) found the special type of band of secondary slip (SBSS) and Wert et al 16) studied it in detail by using EBSD, which was different from KB, and BSS (band of secondary slip) which was called by Honeycombe. 17) In SBSS the quasi-primary slip systems of P2D2 and P2D5 become active instead of the primary slip systems of P1D1 and P1D3 at the initial stage.…”

The h111i rotation recrystallization mechanism, that is the slip band intersection model, presents that a h111i rotation recrystallization nucleus is formed in an intersection part of two kinds of slip bands. The nucleus is obtained by the rotation of the deformed matrix around h111i axis normal to the common cross slip plane of these slip systems. Eight kinds of nuclei are composed of four h111i axes with clockwise and counterclockwise rotations. For these formations in tensile deformation, the operation of slip bands with compressive strain plays an important role. So the operation of twenty-four slip systems including plus and minus directions should be estimated. In tensile deformation, the recrystallization nuclei of h001i, h112i, h111i, and Schmid factor m ¼ 0:5 with kink bands in aluminum single crystals have been estimated and compared with the experimental results, and good relations have been found between them in terms of the selection of kinds of nuclei and their frequency.
