Kikuchi patterns from Electron Backscatter Diffraction of selected phases in S1235. (a) d-QC displaying the 10-fold zone axis. The pattern is clearly distinct from the 5-fold zone axes observed in icosahedral quasicrystals by Asimow et al.⁹. (b) Unindexed pattern of cubic phase. Note the faint superposed double-band running from upper-left to lower-center. (c) Indexing of pattern from (b) as Pm $\bar{3}$ m B2 (CsCl) structured cubic phase, with the green band representing the (111) plane highlighted as the narrow member of the double-band. (d) Attempt to index pattern from (b) as Im $\bar{3}$ m A2 (bcc) structure, with the red band representing the (222) plane; note that (111) is forbidden in this structure. Hence the EBSD result favors the B2 structure for this phase. (e) EBSD pattern of Al₉Ni₂ phase. (f) Indexing of pattern (e) as monoclinic space group 14.
