Abstract

Particles of an unknown intermetallic phase with the approximate composition Al65Cu25Re10 were observed in a ternary Al-Cu-Re alloy. The structure of this phase was investigated in a transmission electron microscope using the precession electron diffraction (PED) technique. This phase has a hexagonal unit cell with lattice parameters a = 11.029(6) and c = 12.746(1) Å; its crystal symmetry can be described by the P63 (173) space group.
