FEM and nano-beam/ABED. (A) Normalized variance V(k) from the as-quenched and annealed Zr₅₀Cu₄₅Al₅ MGs (Adapted from ref. [106]. Copyright©2012, American Physical Society). (B) Top panel shows DSC traces (left) and XRD curve (right) of as-spun and as-rolled Ni₆₀Nb₄₀ MGs. Bottom panel shows the variances from FEM measurements and the HRMC simulated models of Ni₆₀Nb₄₀ MGs (Adapted from ref. [107]. Copyright©2018, Elsevier). (C) (top) Annular dark field image taken before, during and after in situ deformation of BMG sample. (bottom) The NBED was performed in the green dashed box with the scale bar of 150 nm. Three patterns show two-fold (orange), four-fold (blue) and zero (yellow) symmetries in different regions (Adapted from ref. [108]. Copyright©2019, Springer Nature). (D) (top left) Schematic shows the experimental procedure of ABED on an icosahedral cluster with a coherent electron beam with a diameter of 0.36 nm. (top right) Examples of the nano-beam size dependence of electron diffraction patterns. (bottom) Experimental (bottom left) and simulated (bottom middle) NBED pattern including two sets of possible rectangle diffraction patterns. (bottom right) Two face-sharing ⟨0, 2, 8, 1⟩ polyhedra with a common on-axis orientation for Bragg diffraction (Adapted from ref. [44]. Copyright©2011, Springer Nature). (E) (top) Experimental (left) and simulated (middle) ABED patterns of an ideal icosahedron model (right) in 5-fold direction. (middle) The experimental (left), simulated (middle) ABED pattern and distorted icosahedron model (right) from Zr₈₀Pt₂₀ with six diffraction spots. (bottom) The correlation of distorted icosahedron with local fcc symmetry (Adapted from ref. [109]. Copyright©2013, American Association for the Advancement of Science).
