“…The material was received in the form of rolled sheets of 1.5 mm thick, and the same one as used in the previous studies. 14,15) The as-received sheets had been manufactured by the process of casting, homogenizing (at 803 K), hot rolling, cold rolling with a reduction of 75% and a final continuous annealing at 673 K. Workpiece was machined with a 500 mm length, a 20 mm width and a 1.5 mm thickness, and then was cyclic-bent continuously using a specially-designed device up to the number of passes, N CCB ¼ 50. The cumulative true strain is estimated as 5.28.…”

“…14) This straining technique with cyclic deformation leads to a definite difference in strain between the surface and central layers. It was reported that the CCB and subsequent annealing made it possible to produce the gradient microstructure with the coarse-grained surface and the fine-grained central layers in an Al-4.7%Mg-0.7%Mn alloy (A5083) 15) and commercial purity titanium sheets.…”

The relation between the stored energy and the Taylor factor (TF) has been investigated using the SEM/EBSP analysis in an Al-Mg-Mn alloy sheet worked by the continuous cyclic bending (CCB). The analysis reveals that the stored energy is high for the high TF region, whereas a significant increase of the stored energy with the decrease of the Taylor factor appears in the vicinity of the minimum TF value of 2. This observation is discussed using the Schmid factor calculated. Further, the local strain accommodation during deformation is analyzed for grains of different orientations. The stored energy is derived from the calculation based on the kernel average misorientation (KAM).

“…The as-received sheet was produced through an ordinary industrial process. The sheet had been manufactured by the process of casting, homogenizing at 803 K, hot rolling, cold rolling with a reduction of 75% and a final continuous annealing at 673 K. Workpiece was machined with a 500 mm length, a 20 mm width and a 1.5 mm thickness, and then subjected to CCB using a specially designed device 6,7) up to the number of passes, N CCB = 20. The CCB passes were carried out on both sides of the sheet alternately to keep the symmetry of straining.…”

“…Moreover, the formation of microstructure in the coarse-grained layers was found to be related with sharpening of cube texture. 7) High temperature deformation of the sheet with the coarsegrained surface and the fine-grained center layers is supposed to show both characteristics of the fine-grained and the Class I superplasticity. Examining the deformation behavior may reveal the difference in mechanism between the two types of superplasticity or contribution of grain boundary sliding.…”

High temperature deformation and fracture of the Al-Mg-Mn sheet consisting with the coarse-grained surface and the fine-grained center layers have been investigated. Such a microstructure was produced by the continuous cyclic bending (CCB) and the subsequent annealing. The elongation to failure has a peak value at 713 K at initial strain rates of 5.6 × 10 −4 s −1 and 5.6 × 10 −3 s −1 in both of as-received sample (0P) with fine grains and CCBent and annealed one (20P A) with the coarse and the fine grains in spite of different microstructures. The m value decreases for 20P A and increases for 0P with increasing temperature. However, the increase of the m value is not correspondent to the change in the elongation. Deformation mechanism is discussed with activation energy. The SEM micrographs of original surfaces of tensile specimen deformed to failure reveal that at the relatively high temperatures many cracks are formed inside the coarse grains. The features of fractured surface for the 20P A sample reflect the coarse-and the fine-grained layers faithfully.
