Abstract

We present the first complete stereographic projection (Kikuchi band map) of the Al-Mn decagonal phase, determined from tilting experiments using selected- area diffraction (SAD) and convergent-beam diffraction (CBD). These new crystallographic data are indexed with existing schemes. A partial stereographic projection of a phase closely related to the decagonal phase, previously identified as orthorhombic Al3Mn, is also determined with SAD and CBD. Good agreement between the stereographic projection and the SADs for Al3Mn and those for the decagonal phase is demonstrated, indicating the degree to which the Al3Mn phase is a decagonal approximate.
