摘要：
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).
