Fig.1 TEM images (a, c) and sketches (b, d) showing a lamellar structure (a, b) and a twin block structure based on the experimental data reported in Ref.[27] (c, d) of the ARB-deformed Mg-3Gd alloy (RD—rolling direction, ND—normal direction, ARB—accumulative roll-bonding, LBs—lamellar boundaries, LAB—low-angle boundary, TB—twin boundary, SF—stacking fault. Inset in Fig.1d shows the corresponding electron diffraction pattern of a deformation twin (T1) and matrix)
