Abstract
Electron diffraction patterns from a-AIFeSi and αT-AlFeSi are compared. Unusual Kikuchi band patterns are found in both a and αT. Structure factor calculations can be used to explain these patterns. Additional higher order Laue zone (HOLZ) rings are seen in αT. Reflections located at n/9[521] are seen in some zero order Laue zones (ZOLZ) in αT. These additional reflections are responsible for the additional HOLZ rings found in αT. Most atomic positions in a and αT are similar. The specific structural feature which causes the additional reflections in αT is not known. Lattice imaging and image calculation will be necessary to determine the exact structure of αT.
